Hi Bogdan,
I tried replacing the rand() function in that line, but afterwards I got
a core file at another line. Still with SIGILL.
But I think I've found a solution: In "Makefile.defs", for i386 with gcc
3.x I removed the following line (line 592):
-march=$(CPU_TYPE)
CPU_TYPE would be set to "prescott" in that case, but the manpage of gcc
states prescott is "Improved version of Intel Pentium4 CPU...". My
machine is a Pentium III, so it doesn't understand the P4 code generated
by gcc. I recompiled openser without "-march" and it seems everything
works fine now.
I think the Makefile still needs to be fixed for the other architectures
and gcc versions.
Regards,
Christian

Hi Christian,
The line the trace refer at is:
sec_rand[i] = 32 + (int)(95.0 * rand() / (RAND_MAX + 1.0));
I suspect the rand() function, as there were some previous reports
about it....:(
Could you try alter the code and replace the rand() with some number
just to see if it won't crash?

Bogdan

All other messages I get are either DBG or INFO, no errors. But now I
tried something different. I've set "fork=no", and now I'm getting a
corefile. Backtrace of gdb is:

(gdb)
Looks like calling init_mod() recursively. I didn't study the openser
code, but this backtrace looks strange to me.
If anybody is interested in the whole corefile, please mail me
directly. I don't want to post such a large file to the list.
Thanks a lot for your help,
Christian

Hi Christian,
Any logs from openser during startup? if not, try to enable debug
(debug=6) and see where is stops.
