Can you set memdbg and memlog lower than debug and reproduce the case 
again? That results in logging all memory operations, as I need to know 
what part of code allocated previous fragment, because it does a 
overflow write, going over the head of next fragment, thus corrupting it 
structure.

All logs from start to stop are required in this case, so it can be 
quite big file. You can email directly to me or provide some temporary 
access to troubleshoot the system (if that is a more convenient option).

Cheers,
Daniel
