[llvm-dev] bugzilla complaining about "unexpected error"

Tue Oct 5 04:53:34 PDT 2021

Looks like there's an upstream bug report regarding "undef error - This
shouldn't happen at /usr/share/perl/5.18/Text/Wrap.pm line 84.":
https://github.com/Perl/perl5/issues/13447
https://rt.cpan.org/Public/Bug/Display.html?id=124024

If I had to guess, it's triggered for Mikael's issues due to the bug title
style, which have very very long "words" (e.g.
"-passes='loop-mssa(canon-freeze,loop-rotate),function(bounds-checking)'").

As a workaround, I'd suggest not putting the reproduction command-lines in
the bug title.
