[Olsr-dev] Floating Point Exceptions with tip of http://gredler.at/hg/olsrd

[Bernd Petrovitsch]

Hi!

I get deterministically a SIGFPE with the tip of
http://gredler.at/hg/olsrd.

gdb rells me:
----  snip  ----
-- ALL PLUGINS LOADED! --

Warning: probably sizeof(pointer) in strscpy(0x8eb0750, gaz, 4)!
Warning: probably sizeof(pointer) in strscpy(0x8ef08d0, geb, 4)!
Warning: probably sizeof(pointer) in strscpy(0x8ef5140, geb, 4)!

Program received signal SIGFPE, Arithmetic exception.

I'm probably just blind that I don't see any possible problem (and have
no time ATM to investigate more).
