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

Tue Oct 5 05:16:07 PDT 2021

Aha, yes maybe that's it. I'll try to keep the length down then and see.

Thanks for the suggestion,
Mikael

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://protect2.fireeye.com/v1/url?k=b611a2e5-e98a9bc8-b611e27e-8692dc8284cb-32d911d60dac7d07&q=1&e=69b411b6-cfcb-416e-ba34-8d48e0e51b9c&u=https%3A%2F%2Fgithub.com%2FPerl%2Fperl5%2Fissues%2F13447>
https://rt.cpan.org/Public/Bug/Display.html?id=124024<https://protect2.fireeye.com/v1/url?k=94a2b6b7-cb398f9a-94a2f62c-8692dc8284cb-f3c068d170cb96f5&q=1&e=69b411b6-cfcb-416e-ba34-8d48e0e51b9c&u=https%3A%2F%2Frt.cpan.org%2FPublic%2FBug%2FDisplay.html%3Fid%3D124024>

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.

I haven't seen any email notifications related to your updates to PR51946 today. That is quite annoying.
