Hello,
can you reproduce it always?
If yes, looks like a buffer overflow somewhere -- recompile with MEMDBG=1, like:
make cfg MEMDBG=1 ...
(add your specific compile config options as well)
Then run with core parameters memdbg and memlog having values lower than debug. Get all the log messages and send them to me (or a link where can be downloaded).
Cheers, Daniel
