| 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
