Package: libthread-pool-simple-perl
Version: 0.23-1
Severity: serious
Hi,
libthread-pool-simple-perl's tests sometimes go into a deadlock when
running inside fakeroot.
This can be reproduced by running:
~/libthread-pool-simple-perl-0.23# while fakeroot perl t/2.t ; do true; done
The place where it blocks differ each time. For example, I just got it
to block at the following places:
ok 33
ok 12
ok 1 - use Thread::Pool::Simple;
ok 901
stracing the sleeping process gives the following results:
* futex(0x525624, FUTEX_WAIT, 1, NULL
* futex(0x75f3b4, FUTEX_WAIT, 1, NULL
* futex(0x525624, FUTEX_WAIT, 9, NULL
I also got it to block in an msgrcv call, but I couldn't reproduce this
right now.
I could reproduce it:
* in an up to date sid i386 chroot running with an amd64 kernel, on a
2-CPU system, using fakeroot
* on an amd64 system, 2-CPU system, using fakeroot (without any chroot
involved)
I could NOT reproduce it:
* on my laptop (i386, single CPU), even using fakeroot
* without using fakeroot, on amd64
So, I think that it is related to
fakeroot AND (smp OR amd64)
Or maybe it's related to a specific kernel version. My laptop runs
2.6.21-1-686, while the AMD64 I tested it on are running 2.6.18-3-amd64.
I don't have access to an i386 SMP or an AMD64 UP system to investigate
further.

Thanks for checking!

Yup.
Cheers,
