2. Please attach the core file from the troff command that crashed. It will
probably be in your build directory.
3. Also, since the core file might be too large to attach to Savannah, please
collect a backtrace.
Here is a procedure.

##(gdb) quit
I simulated your issue by manually killing troff with SIGILL; I expect your
backtrace to look quite different.
