Thanks again for the debugging! I just sent a patch to the list that
fixes the issue properly. The problem was that afinter had LogDriver as
its parent, while we were casting it from and to LogSrcDriver, which is
a bigger structure.

This resulted in the code overwriting parts of the original LogSrcDriver
parts (such as group_len) with data from AFInterSourceDirver. I changed
the parent to LogSrcDriver and that that fixes the issue properly.

Pinning it down to mark messages helped tremendously! Thanks!
