I agree that knowing where the fault occurs would be helpful now.

If I read the makefile supplied with SIMH correctly, a non-Win32 
compilation already includes debug info (via the "-g" switch):

  CC = gcc -std=c99 -U__STRICT_ANSI__ -g $(OS_CCDEFS) -I .

Brian, if you have gdb on your system, you should be able to start SIMH 
with gdb, issue the gdb "run" command, and then when the segfault occurs, 
issue the gdb "backtrace" command to print the call stack.  This should 
show us where the problem is occuring.
