The following error is seen continuously in my HTTP Error log: MoreUtils.pm: Use of uninitialized value in scalar assignment at lib/i386-linux-thread-multi/List/MoreUtils.pm line 24. Looking at line 24, I see the following assignment: local $ENV{PERL_DL_NONLAZY} = $ENV{PERL_DL_NONLAZY} ? 0 : $ENV{PERL_DL_NONLAZY}; Something about that line looks wrong. If Perl_DL_NONLAZY is non-zero, you set it to 0, otherwise you set it to undef? Why not just call out 'undef' instead? Although, setting it to undef also causes the same error. Seems like a bug to me. Harmless, but certainly annoying. All I can seem to do to get rid of the error is to comment out the line completely. Maybe running under mod_perl in Apache causes $ENV to not get set?

Which version of Perl and which version of List::MoreUtils?

This is perl, v5.8.8 built for i386-linux-thread-multi List::MoreUtils version 0.26 My final, non-warning code is: (copied from List::Util) local $ENV{PERL_DL_NONLAZY} = 0 if $ENV{PERL_DL_NONLAZY};

I'm seeing the same issue and it's causing the Bugzilla QA tests to soft- fail (because they're throwing this warning).

I too am seeing this issue perl 5.8.5 List::MoreUtils 0.29 I'm seeing it from a command-line script so I single-stepped it, resulting in the following output: DB<3> s List::MoreUtils::CODE(0x20ed340)(/usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm:32): 32: local $ENV{PERL_DL_NONLAZY} = $ENV{PERL_DL_NONLAZY} ? 0 : $ENV{PERL_DL_NONLAZY}; DB<3> s Use of uninitialized value in scalar assignment at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 32. at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 32 eval {...} called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 31 List::MoreUtils::BEGIN() called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 eval {...} called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 require List/MoreUtils.pm called at /usr/lib/perl5/site_perl/5.8.5/Package/DeprecationManager.pm line 10 Package::DeprecationManager::BEGIN() called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 eval {...} called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 require Package/DeprecationManager.pm called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/Moose/Deprecated.pm line 22 Moose::Deprecated::BEGIN() called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 eval {...} called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 require Moose/Deprecated.pm called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/Moose.pm line 14 Moose::BEGIN() called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 eval {...} called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 require Moose.pm called at /home/dhoworth/progs/modules/CrossReference.pm line 16 CrossReference::BEGIN() called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 eval {...} called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 require CrossReference.pm called at /home/dhoworth/progs/modules/Efamily/SIFTS.pm line 152 Efamily::SIFTS::BEGIN() called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 eval {...} called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 require Efamily/SIFTS.pm called at progs/ebi/msd/sifts-crossrefs-qd1.pl line 64 main::BEGIN() called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 eval {...} called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 36 List::MoreUtils::CODE(0x20ed340)(/usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm:33): 33: bootstrap List::MoreUtils $VERSION; ;' called at /usr/lib/perl5/5.8.5/perl5db.pl line 620 DB::eval called at /usr/lib/perl5/5.8.5/perl5db.pl line 3292 DB::DB called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/List/MoreUtils.pm line 31 List::MoreUtils::BEGIN() called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 eval {...} called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 require List/MoreUtils.pm called at /usr/lib/perl5/site_perl/5.8.5/Package/DeprecationManager.pm line 10 Package::DeprecationManager::BEGIN() called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 eval {...} called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 require Package/DeprecationManager.pm called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/Moose/Deprecated.pm line 22 Moose::Deprecated::BEGIN() called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 eval {...} called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 require Moose/Deprecated.pm called at /usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/Moose.pm line 14 Moose::BEGIN() called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 eval {...} called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 require Moose.pm called at /home/dhoworth/progs/modules/CrossReference.pm line 16 CrossReference::BEGIN() called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 eval {...} called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 require CrossReference.pm called at /home/dhoworth/progs/modules/Efamily/SIFTS.pm line 152 Efamily::SIFTS::BEGIN() called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 eval {...} called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 require Efamily/SIFTS.pm called at progs/ebi/msd/sifts-crossrefs-qd1.pl line 64 main::BEGIN() called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 eval {...} called at (eval 35)[/usr/lib/perl5/5.8.5/perl5db.pl:620] line 0 HTH, Dave

Also note that this appears to be a duplicate of #63342, which provides more explanation and a suggested fix. There's no commentary on why that fix is not appropriate and/or not applied

This can, and should, be closed. It was fixed in version 0.30 as part of bug 63342.
