<br>
Hello.<br>
<br>
I am working on porting bird 1.4.5 to QNX SP1 (QNX OS service pack 1).<br>
QNX is actually close to BSD and there have been very few changes to the code.<br>
<br>
I have bird built but I get a core dump on initialization.<br>
I was hoping that someone could give me some specific ideas on<br>
exactly where to look while debugging. I have many years of writing and debugging<br>
Linux and Solaris drivers and networking code, but I am not yet familiar<br>
with the bird internal data structures.<br>
<br>
I tried building with and without pthreads.<br>
I get a core dump both ways, in different spots,<br>
both when calling WALK_LIST() with a list.<br>
<br>
// with pthreads<br>
#0 0x00111460 in if_notify_change (c=1, i=0x187050) at ../../nest/iface.c:218<br>
218 WALK_LIST(p, active_proto_list)<br>
<br>
// without pthreads<br>
if_start_update () at ../../nest/iface.c:338<br>
338 WALK_LIST(i, iface_list)<br>
<br>
<br>
I also turned off the '#define POISON' in lib/slab.c,<br>
and on a different run did a bzero() instead of a memset(POISON).<br>
Neither changed the results.<br>
<br>
Attached find my bird.conf<br>
<br>
Any hints would be appreciated.<br>
<o:p> </o:p></span></p>
