Comment 6 for bug 1035572

Hi,
I just make a test if my thoughts are right. On a Wheezy debian i386 I type in comandline
qemu-i386 -strace clonemi
(clonemi is the program testclone but with the endless loops in waitpid at its end put out.)
The result is exact like on Raspberry Pi with ARM 1176 processor.
So you can see, that the error belongs to the try of building TWO threads in the guest i386,
independ which host you have,
Dietmar

PS: Again the parent_tidptr and the child_tidptr are different in the SAME clone(),
but are identic to the values in the other thread with clone(). What does this mean?
