[Valgrind-users] Valgrind Internal Error: Valgrind received a signal 11 (SIGSEGV) - exiting

Hi, I am receiving a valgrind Internal error upon startup of a multi-threaded application. It appears to be related to the option track_origins as I was not seeing the issue without the track_origins option. I am using the following valgrind options: --trace-children=yes and --track-origins=yes. If you have any ideas on how I can workaround this issue or fix it, I would appreciate it. According to valgrind, the 'impossible' happened. See below for the valgrind output associated with this error. Thanks, John Knight Joh...@be...
