Subject: Global destruction detection is not thread-safe
Your distribution is using the construct END { $global_destroy = 1 } in [1], which is not thread safe as described here [2]. Please consider switching to https://metacpan.org/release/Devel-GlobalDestruction, which has both an XS and a PurePerl variant, both of which are tested to behave correctly under ithreads. Cheers [1] http://cpansearch.perl.org/src/MOB/Devel-DumpTrace-0.15/lib/Devel/DumpTrace.pm [2] https://metacpan.org/source/DOY/Devel-GlobalDestruction-0.05/lib/Devel/GlobalDestruction.pm#L36
Adapted techniques from Devel::GlobalDestruction to improve the thread safety of this module.
