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
