This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.35 running under perl v5.8.5.
-----------------------------------------------------------------
[Please enter your report here]
The following test program crashes on a multiprocessor box.
Removing either the line that sets $g_bar or the call to
utf8:upgrade() makes the crash go away.
use threads;
my $g_foo = "abcd\n";
my $g_bar;
($g_bar) = $g_foo =~ /(.*)/;
sub init {
my $thr;
for (my $i = 0; $i < 8; $i++) {
$thr = threads->new(\&task);
}
foreach $thr (threads->list) {
if ($thr->tid && !threads::equal($thr, threads->self)) {
$thr->join;
}
}
}
sub task {
print "task starting\n";
for (my $i = 1; $i < 10000; $i++) {
my $str = "foo=bar baz\n";
utf8::upgrade($str);
if ($str =~ /^([^=]+)=(.*)$/) {
my $a = $1;
}
if ($str =~ /^(foo)(\w*)/) {
my $a = $1;
}
}
}
init();
