Re^5: Variable triggers global destruction hang

But the OP has duplicated the file handle in both cases.

huh?

open FH , "| cat " or die ;
open STDOUT, ">&FH"or die ;    <-- dup
[download]

open FH , "| cat " or die ;
                               <-- no dup
[download]

But the OP says 5.10 hangs with either form

huh? He asked "what is the reason that [the one with duping] hangs while [the one without duping] doesn't?" Clearly, both don't hang for him.

I'm confused. The two cases I see in the original post are: `open FH , "\| cat " ; open STDOUT, ">&FH";` [download] and `my $foo = qr(a); open FH , "\| cat " ; open STDOUT, ">&FH";` [download] FH is duplicated to STDOUT in both cases. And, saintmike said: Just verified: With an old perl-5.8 I get the different behavior with/without the variable, with perl-5.10 it hangs regardless. I took this to mean that with 5.10 it hangs waiting for the sub-process to terminate.	[reply] [d/l] [select]

What makes you think that a reply to Re^3: Variable triggers global destruction hang answers a question in Variable triggers global destruction hang when Re^3: Variable triggers global destruction hang asks a different question?	[reply]

My mistake - I didn't notice that the cases had changed. Sorry for the confusion.	[reply]
