( #3333=superdoc: print w/replies, xml ) Need Help??

Thank you very much for updating and giving your reason. I do in fact use Thread::Conveyor and had never run in to the segfault issue.

Upon investigation, I only get the segfault when I set the stack size globally (when I load the threads module or via threads->set_stack_size(). I have no problems if I set the stack size at thread creation time (below). This explains why I have never run into trouble. Clearly, there is some problem with Thread::Conveyor and you have convinced me that there might be some reason to avoid it. Determining whether the problem is fixable is probably beyond me.

#! perl -slw # This is perl, v5.10.1 (*) built for x86_64-linux-gnu-thread-multi use strict; use threads; use Thread::Conveyor; my $belt = Thread::Conveyor->new( { maxboxes => 50, minboxes => 25, optimize => 'memory', # or 'cpu' }); threads->new(sub { print while defined( $_ = $belt->take ); }, { stack_size => 4096 })->detach; $belt->put( $_ ) for 1 .. 10; $belt->put( undef );

Good Day,
