gcc3.0.1/HPUX

[thomas.porschberg@osp-dd.de]

I wrote a typical batch program with gcc3.0.1 on HPUX which runs a
relatively long time, say about 3 hours.
The programs reads data units from a file and put the data in a database.
Curious, sometimes it "hangs". This means I see the assoziated process,
the process does not cause load on the machine, the program is not
blocked by database locks.
If I attach to the process with GNU gdb (5.0) and do a "info stack"
I see only

#0  0xc01f4c40 in ?? () from /usr/lib/libc.2
#1  0xc0200bf4 in ?? () from /usr/lib/libc.2

How can I isolate the problem further?
