Hi

I have a problem whith Alpha SMP's which seems to be kernel-related. I
discussed this on the bug-glibc list but everybody seems to agree that
it cannot be a libc problem.

I attached a little testprogram which reproduces the bug in < 1Minute. 
BUT: IT MUST BE STARTED AT LEAST TWICE!

The strange thing is that a single instance of the program runs just
fine. When I start the program a second time, I get segfaults and/or
stuck threads.

We could reproduce this behaviour on different Machines, both with linux
2.2.14 and 2.4.0-test10, but 
ONLY ON ALPHA SMP MACHINES.

Here's my configuration:

Linux reto1 2.4.0-test10 #2 SMP Tue Oct 31 19:39:51 PST 2000 alpha
unknown

Any ideas?

Please tell me when you need more information, or give me some pointers
where I could start to dig...

TIA
