Hi all

I continue to have the problem described above on all linux - x86
platforms I've
ever used so far (including glibc2.1, 2.2) and different distributions,
i.e. Redhat,
Slackware, Debian and so on. The strace above has been generated on a
Debian Woody, Kernel 2.2.19 with elf binary support directly included
(not as
a module).

Is there anybody who can give me a hint what's going on? I've used the
same beta distribution on sparc based systems (linux/solaris) and it
works
with no problems at all. Am I missing anything?

thanks in advance
Stefan
