Subject: Re: gcc optimizations and threads (pthread)
thanks for the quick reply.
But this code works without opimizations. Even with complex constructs.
For the solution of my problem i can't use lock's.
I don't want so serialize the threads, I want to use all 2 processors of my
dual-core.
And for syncing the threads, that's the easiest way.
Works fine whithout optimizations and also works with borland c++-compiler with
all optimizations.
