note MeowChow Interestingly, this causes both my 5.6 Win32 ActiveState Perl and my 5.6.1 Linux to segfault, but appears to work under 5.00503. Hmmm.... <p> <b>update</b>: I think this is a garbage-collection issue, stemming from your deletion of a hash key will simultaneously dereferencing it. Ingenious, and dangerous. <p> <b>update2</b>: Err, that wasn't the problem, the problem was that my test hash was already %t, so it was getting reset inside the sub, and I ran into [id://80448|this]. <pre> <a href="/index.pl?node=MeowChow"> MeowChow </a> s aamecha.s a..a\u$&owag.print</pre> 80272 80433
