first of all: greeting from the biggest<br>
olsrd2-testnet in the world 8-) with 70 real nodes.<br>
<br>
and: what is the best place for such reports?<br>
for now i have this on different platforms<br>

warning: GDB can't find the start of the function at 0x40c358.<br>
<br>
GDB is unable to find the start of the function at 0x40c358<br>
and thus can't determine the size of that function's stack frame.<br>
This means that GDB may be unable to access that stack frame, or<br>
the frames below it.<br>
This problem is most likely caused by an invalid program counter or<br>
stack pointer.<br>
However, if you think GDB should simply search farther back<br>
from 0x40c358 for code which looks like the beginning of a<br>
function, you can increase the range of the search using the `set<br>
heuristic-fence-post' command.<br>
