It is jumping before the function AAC_DetectHostadapter, where there are
0 bytes. Two 0 bytes are "add %al,(%eax)" in x86. It is crashing
because %eax does not contain a valid pointer (but 25).

Now you just have to find out why you're jumping to the bogus pointer.
It could e.g. be caused by a stack overwrite.

Hope that helps,
