Apparently this happens when our process receives a SIGSEGV. We have mapped SIGSEGV (and other signals) to perform logging, memory free and other cleanup before killing the process. Then we remap the SIGSEGV to default behavior and send a SIGSEGV signal to kill the process.
It seems to work fine but sometimes it doesn't. The crash occurs during the cleanup process. Any reason for why the crash could be happening from the logs?
