[muscle] Re: QMutex::lock() segfaults - SOLVED

After recompiling Qt with debug information (which did not give a lot of 
additional information), I also attempted to rebuild glibc at my end, but 
that did not solve it.

I took a big breath and stepped back and upgraded to 2.45. In addition, I 
tried adding the MUSCLE .cpp file dependencies directly, so that they got 
compiled into my application instead of linked in through a static library. 
After doing this, it works. 

In short, I am not sure why, but at least I got it working. I would speculate 
that different compiler options when compiling MUSCLE on its own and stuffing 
the object files into a library file that was then linked to my Qt based 
client is to blame.

Thanks for the help anyway.

Regards,

Marius K.
