This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.35 running under perl v5.8.6.
-----------------------------------------------------------------
Throwing an exception inside a grep sometimes causes Perl
to emit an internal warning.
$ perl -e 'for ("foo") { grep(die, "bar") }'
Died at -e line 1.
Attempt to free unreferenced scalar: SV 0x96c61dc, Perl interpreter: 0x96ae008.
Does this warning indicate possible internal corruption? I have seen
some Perl corruption in a production system at my work recently, as well
as this warning, so I wondered if they could be related.
[Please do not change anything below this line]
