While RAM bugs might be fun to chase, my money is that this is an
assembler bug.  If you can't upgrade the whole OS, at least pick up
tls706 from ftp://ftp.sco.com/TLS/ to get a fixed assembler.

It finishes only becuase it leaves a corrupted object.   exception.o
is toast and attempts to use it will result in punishment.

This is a hint that someone is using "-belf" to GCC ("look in a
directory named elf".  This would be wrong; -belf is a valid flag to
/bin/cc and not for GCC.  GCC spells that flag "-melf".  Find where this
is coming from and fix it.  Bonus points for doing it before the 2.95.3
release.
