In perl5.10 the behaviour of a die handler is inconsistent: 

$SIG{__DIE__} = sub { print "\$@='$@'\n"; $@='' };

eval {die "string" };
print "\$@='$@'\n";

eval {die { } };
print "\$@='$@'\n";

If the die gets passed a string, the signal handler has a local $@ which is empty, and modifying it doesn't affect the caller. If it gets passed a hashref, it doesn't localize it, and modifying it (calling eval inside sigdie) changes it in the caller's scope.

I know it was fixed by 5.18. I've tried finding it in perldelta, but I think I'm searching for the wrong thing. Does anyone know which Perl version this was fixed in? Thanks.

edit: missing semicolon
