The DEBUG_MALLOC option enables additional functions within batman that allow 
it to easily trace back malloc bugs. A simple core dump might help but 
sometimes it is hard to say where it is coming from. Could you post the exact 
"invalid trailer number" line ?

I'm a bit confused here:
* Is batman crashing ?
* Is the kernel crashing ?
* Is batman crashing if you use the batgat module ?
