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

The crash I showed was with a hand-compiled Xaw3d with debug info
(actually an Xaw3d with some local changes so that you can dynamically
choose the Xaw-style or the motif-arrow-style scrollbars).  But the
backtrace is in Xt code, not in Xaw(3d) code.


XtInitializeWidgetClass (where it crashed), fills in the widget class structure. I guess something in the widget description is wrong, such as saying sizeof(int), where sizeof(double) is intended, or OffsetOf points to the wrong member. If you have local changes, there is a good place to start looking.

This is hard to see without a debug compiled Xt. Doesn't Debian have separate debug-infos that you can install for Xt?
