[M3devel] problem using -DPTHREAD

[Tony Hosking]

A stack trace would be useful.  Perhaps you can run again with  
@M3stackdump specified on the command line.  Alternatively, if you  
run inside gdb you can show the stack dump at the point of the error  
by setting a breakpoint at line 168 in ThreadPThread.m3.

I notice that you are using priority scheduling -- not sure what that  
will do to things.  Can you try it with round robin scheduling?
