Henrik,

here's the output:

#0  0xc020d5b8 in _kill () from /usr/lib/libc.2
#0  0xc020d5b8 in _kill () from /usr/lib/libc.2

(gdb) p used
$1 = 1074320844
(gdb) p needed
$2 = 1024
(gdb) p bufsz

(gdb) p buf
$5 = (char *) 0x8c70 "\b\034\002X\204`!0\013\205\n%4\023"
(gdb)  

Thanks, Chris.

Very odd. The interesting thing is that hobbitd here is doing a 
re-allocation of a buffer, but asking for 0 bytes - and apparently,
HP-UX doesn't like that.

But I don't see how it can get to asking for 0 bytes in that part
of the code...

Could you start gdb again, but instead of the "bt" command do this:

gdb> fr 10
gdb> p used
gdb> p needed
gdb> p bufsz
gdb> p bufp
gdb> p buf


and mail me the output?


Thanks,
Henrik
