Package: liblist-moreutils-perl
Version: 0.22-1+b1
Severity: normal
File: /usr/lib/perl5/List/MoreUtils.pm
$ cat t.pl
use List::MoreUtils qw(mesh);
&mesh($foo, $bar);
$ perl t.pl
Segmentation fault
An error message would be much better. The pure pure implementation does
not seem to suffer from this problem; only the XS version.
Here is a backtrace using perl-debug:
