Re: Mysterious acts of 3.1

Hi Amos,

I am going to take a swing at things here and say it something to do with
the thread that you create. Something (some global variable etc) is not
locked in a mutex or you are using a non-thread-safe function/procedure.
It's most likely in the first couple of lines of the function/procedure that
starts the thread.

I did a bit of work on threads using C, not C++ so my advise is a bit
shaken...if not stired :)

Cheers,

Pieter
