I can't reproduce this.  I used your configure flags, and tried with Xaw3d and 
straight Xaw.  I guess it is some memory corruption or aligment problem.  Can 
you compile without Xaw3d and just use standard Xaw?  You don't have that gcc 
4.4 memcpy bug?  Does it happen wih -O0 also?

If you compiled Xaw3d yourself, recompile it with debug and run gdb to the crash.
