I have a large application program that is written C and runs under
HP-UX 7.0 on an HP 360. Part of the application is a yacc generated
compiler.  Compile times are long, so I planned to profile the code to
see where it could be optimized.

I compiled all of the source files for the application with the "-G"
option so I could use gprof(1).  When I run the program I immediately
get a bus error and core dump. I tried using the "-p" option to use
prof(1), and I still have the problem. If I only compile the source
file containing the routines I want to profile, the bus error still
occurs.

From the debugger, I have been able to determine that the bus error
occurs before the application executes the first line in main(). It is
somewhere in the routine "mcount" which I believe is part of the
profiler code (but it is a library routine so I do not have source).

Any ideas on what the problem is and how it can be solved?
