| Subject: | panic: attempt to copy value Future=... to a freed scalar |
Been seeing variations of this message on 5.16.x for a while, particularly when debugging (and thus, Carp shortmess compexity) is enabled. However, it appears to be possible to trigger it on 5.20.0 even without PERL_FUTURE_DEBUG set.
This seems unfortunate, but perhaps it's fixed in 5.20.2... here's a failing script, maybe I'm doing something wrong here?
cheers,
Tom
