This is a bug report for perl from fvw@var.cx,
generated with the help of perlbug 1.35 running under perl v5.8.8.
-----------------------------------------------------------------
[Please enter your report here]
[gbc1-dev-01:/home/fvw] perl -e 'for (1) { my @x=(1); map {die } @x; }'
Died at -e line 1.
Attempt to free temp prematurely: SV 0x8166d6c, Perl interpreter: 0x8166008.
Attempt to free unreferenced scalar: SV 0x8166d6c, Perl interpreter: 0x8166008.
In this case the loop iterator gets made mortal in Perl_dounwind, but then
its refcount drops to zero before the freetmp.
This doesn't happen on 5.10.0, but I'm not sure if that's due to a fix
or just because of the other sv changes.
[Please do not change anything below this line]
