Hi Thomas,

I'm sorry but I can't reproduce the problem on Linux since I don't have a
Linux machine available.

I am completely sure that the thread settings (-D_REENTRANT -pthread) for
the compiler are set. Please have a look at the MakeFile that is attached to
this e-mail to make sure that I've set everything fine.

After your last instructions, here is the debug output:

I hope this helps.
