Segment Fault when creating a thread
I must have a problem with my mod_perl set up. When I try to run this script, I get a "child pid 451 exit signal Segmentation fault (11)". It seems that creating the thread causes the error. This is the startup line from the log file with the apache, mod_perl, and perl versions.
Apache/2.2.11 (Unix) mod_perl/2.0.4 Perl/v5.8.5 configured -- resuming normal operations
The script that causes a failure is
#!/usr/bin/perl -wT
use strict;
use threads;
use threads::shared;
my $temp = threads->new(\&foo,"mike");
exit;
sub foo {
my $input = shift;
my $number = int(rand(10));
print "this went in the thread\n";
return($number);
}

I'm not that knowledgeable on threads, but this guy managed to get the
working with mpm_worker a month or so ago:
http://www.gossamer-threads.com/lists/modperl/modperl/103420
That is still a rather old version of Perl, so I would suggest trying
5.10 or something newer.
