[Ace-users] ACE core on exit()

Hi,

I am getting the following core when the system is calling exit():

Anyone had a similar experience on this problem? I feel like it might
be related to mutex as we use guard in the code. But knowing very
little on ACE, I don't know how to track down the root cause.

Thanks for help!
