I am indeed back now, and I'd be happy to look at it, but I don't have
access to a RedHat 7.3 system.

The first thing to do would be to see whether the Boehm collector
passes `make test' -- for both the version shipped with the Mercury
compiler, and also the latest version on Hans' web site:
<http://www.hpl.hp.com/personal/Hans_Boehm/gc/>.
If the former fails, and the latter doesn't,
then the solution will be to merge the recent changes
into the GC.

Otherwise, it would help to know exactly where it is failing.
The stack trace that you get for the seg fault may be more accurate
if you add the following text

	EXTRA_MGNUCFLAGS = --c-debug --no-c-optimize
	EXTRA_MLFLAGS = --c-debug                                                       
to the file Mmake.params before building from the source distribution.
