expresso (probably) is getting the memory fault, the shell is just reporting
about it.   A memory fault is usually caused by a bad pointer of going off
the end of an array.

If the program (expresso) has write permission in the directory that it
is running in and it can write a 'core' file, the message would have 
been something like "memory fault - core dumped".  You could take
the executable and the core file and use a debugger (dbx, sdb, adb)
to find out what is causing the problem.
