| Subject: | Devel::Declare fails to load |
On one machine, I get an illegal instruction when trying to load the module:
$ perl -MDevel::Declare -le 'print "hello"'
Illegal instruction
The above would work if I try to load symbols earlier, i.e.
$ LD_BIND_NOW=yes perl -MDevel::Declare -le 'print "hello"'
hello
$ PERL_DL_NONLAZY=1 perl -MDevel::Declare -le 'print "hello"'
hello
