No code, no instructions, no information. Just a screenshot of a perl process crashing.
What exactly do you expect us to do with this ticket?

@philiprbrenan, this ticket is an inappropriate use of https://github.com/Perl/perl5/issues. This is not a Perl help site, i.e., it is not a site one should turn to when one can't figure out what's going wrong with one's program. It is a site for analyzing problems with the Perl programming language and its ongoing development. Filing tickets like this one here simply wastes everyone's time, including your own. Please do not file such tickets here in the future.

But he was reporting a SEGV, which perl isn't supposed to do. That means that its either a bug in perl or (more likely) in some included XS code. Which means it is an appropriate issue to raise. The main criticism seems to be the lack of information about how to reproduce the bug.
