in reply to panic: attempt to copy freed scalar a7b9650 to ad20598

We got this same symptom today, using Try::Tiny 0.04:

Attempt to free unreferenced scalar: SV 0x82d1fa0 at lib/Try/Tiny.pm l
+ine 76.
Attempt to free unreferenced scalar: SV 0x82d1fc0 at lib/Try/Tiny.pm l

Attempt to free unreferenced scalar: SV 0x83d4080 at lib/Try/Tiny.pm l
+ine 76.

We haven't found the root cause yet.

I should mention: We are using Perl 5.8.8 on that server. Also, here's a third case of it happening, in the Fennec test suite. Search through CPAN tester data via Google may find more:	[reply]

In my case there was no problem in Try::Tiny but I had declared a variable like this `my $thing if (some_test);` which is really bad. The changes I made to introduce Try::Tiny seemed to have triggered the error to be seen.	[reply] [d/l]
