| 
| Is there anyone else out there running IRIX 5.2 with ACL 4.2 final and CLIM
| 2.0 on both R4000 and R3000 machines?  Are you experiencing any problems
| running CLIM on your R3000 machines?  We built our image on an R4000 and we
| experience signal 10 bus errors on the R3000 intermittently when using CLIM.
| As most of our development work is done on R3000 machines, this will be a
| major difficulty.  Has anyone else had similar problems?  More importantly,
| does anyone have any solutions?   ;-)

| I found that the accepting-values form with an accept on a string was
| receiving a null value where it should have had a string.  That was causing
| our signal 10 bus errors.  Sorry to have brought this up.  We are getting
| used to the new interface to MOTIF and given the context of the problems we
| had with the alpha version we were not looking for type compatibility
| problems.  I will be sensitive to this type of error causing bus errors in
| the future.

Glad you figured this out, and apologies for the unfriendliness of the
error message.  The bus error resulted from an over-optimization in
our stream-write-string code, which was racing ahead without checking
that it had indeed been handed a string.  This has been fixed for the
next release, and I'm in the process of putting together a patch,
which I'll have sent to you (and which will appear on our ftp patch
site as well soon).
