https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=261690 --- Comment #1 from Björn Fischer <bf@cebitec.uni-bielefeld.de> --- Ok, I found a way to trigger the problem with this silly perl script on the Linux client, so no need to pull off a complete GCC bootstrap: #!/usr/bin/perl use strict; use warnings; use threads; use IO::Handle; use Fcntl qw(SEEK_SET SEEK_CUR SEEK_END); my $testfile = 'testfile'; my $thread = {}; map { $thread->{$_} = threads->create( sub { open(my $fh, '+>', $testfile) or die "Can't open +> $testfile: $!"; my $id = $_; map { seek $fh, int(rand(1024*4096)), SEEK_SET; print $fh 'foobar' x (500 + int(rand(4000))); $fh->flush(); } (0..10000); close $fh; } ) } (0..1000); map { $thread->{$_}->join(); } (0..1000); -- You are receiving this mail because: You are the assignee for the bug.
