This problem manifests on an Indigo. On a Onyx RE I don't get the error
message, but still have problems. All my compilers and libraries are
current releases.

I wish. It's about 200 kloc of code, mixed C++, ANSI C, K&R C, and
Fortran. The Fortran is -align16. I suspect that the executable is not
being made properly (bad C prototype or alignment). Visually, I have four
wide ragged horizontal bands of rogue haze. After making some (apparently)
unrelated changes the haze went away, but some other changes and now it is
back again.
If I crawl around in the program using dbx I reach a call to gversion(), the
code then magically jumps to the line of code three lines above, next it
executes the gversion() line again, then hurls. No core file is
generated. On an Onyx RE it doesn't crash. It bus errors just on the
Indigo.
I don't expect you to debug this for me, just wondered if the unusual
error message at the console is a clue.
One more question, what libraries am I supposed to have when I build
using -align? Do I need to call handle_unaligned_traps()? If so, what is
its include file?
Thanks.
Robin
