Thanks for the trace you sent me. It would really help if you could send me the core file with the equivalent executable, and report the exact snapshot you used. I think that this crash explains why it randomly fails. Something is not working as expected, and when we're lucky, it crashes, but when we're unlucky, it probably silently uses an incorrect memory location explaining why the rest of the processing fails. The patch that was discussed in the thread you mentionned had no reason for changing anything, instead of clearing the errors unconditionally, it only cleared them if there were any. It's more of an optimization and the fact that it changed something indicates that we have a random bug somewhere. And your trace proves that ! Thanks, Willy
