Hello esteemed monks,

I tried to gather coverage for our project at work and there were a lot of messages like follows:

unexpected OP_CUSTOM (catch) at /home/lodin/perl5/perlbrew/perls/perl-5.26.3/lib/5.26.3/B/Deparse.pm line 1667.

Not only that, but the build now takes several hours instead of ~20 minutes (the project uses S::K::T extensively and has lots of tests), that is a considerable slowdown. If the error message is not there, the covered build only takes an hour or so.

Reproduction is as simple as 

cpanm Devel::Cover
cd Syntax-Keyword-Try-0.11
perl Build.PL
HARNESS_PERL_SWITCHES=-MDevel::Cover ./Build test

[download]

I managed to find out that it happens when using Syntax::Keyword::Try >0.10 (lower versions are ok). I also found a bug on github about similar message but it was fixed 2 years ago.

What should I do next? Should I report a bug in S::K::T? Devel::Cover?

Thank you
