Thanks go to Tom McSorley for pointing me in the right direction.
He sent me a message which (basically) said:
| I experienced a similar problem to that indicated above.  All worked
| well under 2.x (not verifiable).  The application ran fine without
| the MallocDebug lib linked in under 3.0, however with the MallocDebug
| lib linked in, the application SEGMENTATION FAULTED immediately.
| Debugging this condition showed that the problem occurred before it
| ever got to any of my code -- therefore the problem was within the
| NIB file load and initialization.
| ... What it turned out to be was that the User Interface Guy used
| some fonts in his NIB file construction that were not present on the
| other system.  When we changed the fonts back to a system default font
| the SEGMENTATION FAULT disappeared.

In my case KPerfMon had two NIB files.  I removed an (unused) Services menu  
from the first, and fiddled around with the fonts in the second one (though  
I don't think I actually *changed* any fonts).  MallocDebug then worked like  
a charm.

I don't know if it was the fiddling I did, or if the NIB files just needed  
to be saved under a NS3.0 system...  In any case, I hope this info proves  
useful to anyone else who runs into a similar problem.  MallocDebug is  
pretty useful, now that I have the hang of it...
