[gtkmm] Glib::Thread and stack size

[Enrico Costanza <ec142 york ac uk>]

Hello.

I have finally threads up and running. I have the "main thread" deaing 
with gtkmm and a separate thread grabbing images from a video device, 
and communicating with the GUI with a instance of the Glib::Dispatcher.
Unfortunately, I still have some problems with them.

When I try to do some image processing in the thread, I get a 
segmentation fault.
It seems that troubles are coming from the thread stack size. I have 
tried to set the thread stack size manually using
Glib::Thread::create (const SigC::Slot0<void>& slot, unsigned long 
stack_size, bool joinable, bool bound, ThreadPriority priority)

But if I set the stack size to more than 8000000 create(..) does not return.

Why is that? Any suggestion?


Thank you very much -once again- in advance.
