I have a client server application with multi-threading. The server side is failing with a std::list getting corrupted resulting in a SEGV. I suspect that there is some kind of cross thread timing issue going on where the two threads are updating the std::list at the same time and causing it to be corrupted.

Please suggest free tools to track this down or strategies that might be helpful.

When a message is dealt with by the consumer, it is removed from the list using pop_front(). But, during pop_front, there is a core dump. The gdb trace is as below. could you… >>> More
