Strange. The segfault happens if the test suite runs within the CPAN.pm shell (i.e. with /opt/perl-5.20.3D/bin/cpan -t ETHER/Sub-Name-0.24-TRIAL.tar.gz ), but I cannot reproduce it anymore if doing a "make test" in the build directory.

A backtrace from the core dump, but does not look very helpful: (gdb) bt #0 0x00000000004aec4c in Perl_sv_clear () #1 0x00000000004af4ef in Perl_sv_free2 () #2 0x00000000004a7132 in S_visit () #3 0x00000000004af8fc in Perl_sv_clean_objs () #4 0x00000000004378d8 in perl_destruct () #5 0x000000000041de64 in main ()

The proper fix here will most likely be to have subname refuse to name lexical subs on perl 5.18 and 5.20. As far as I know it isn't possible to name lexical subs on those versions, but we still shouldn't be segfaulting.
