Nobody has a solution ?

It is really important for the application not to crash and still reacting (so not waiting for the thread termination that depends on the gSOAP ending its HTTP call) when I close a windows.

I can't use on the heap allocation for the threads because Qt doesn't really like that (I've got error messages related to QMutex).

The problem is really with the terminate() call that works on Windows but leads to a segmentation fault on an UNIX system.
