Hi,<br>
<br>
thank you for the bugreport, I would like to dig a little bit deeper<br>
into this problem (maybe writing an automatic test-case afterwards).<br>
<br>
Can you post the whole stacktrace from GDB first? That would allow to<br>
identify if the error happens during the creation of a Hello or a TC.<br>

Hello,<br>
<br>
I am running olsrd2 on a few (qemu) virtual machines. On one of the virtual<br>
machines, olsrd2 segfaults within a few seconds. I am invoking OLSRd2 in the<br>
following manner,<br>
<br>
./olsrd2 --set interface[eth0].bindto=<a href="http://10.0.0.0/8" target="_blank">10.0.0.<u></u>0/8</a> --set<br>
interface[eth1].bindto=<a href="http://10.0.0.0/8" target="_blank">10.0.0.<u></u>0/8</a> --set interface[eth2].bindto=<a href="http://10.0.0.0/8" target="_blank">10.0.0.<u></u>0/8</a><br>
<br>
Traced the error using gdb to some extent. Please see the following patch<br>
for context.<br>
<br>
In general, addr_start->_block_end becomes NULL just before exiting from the<br>
do..while loop. However, in some cases, addr_start->_block_end becomes NULL<br>
before the do..while loop meeting the exit criteria (addr_end == last_addr).<br>
So, the loop continues and trying to de-reference NULL pointer causing<br>
segfault.<br>
