Here is some information on making OLS work on a Silicon Graphics
box.  Thanks to Tim Monks for giving me the dope.

---------------------------------------------------------------------------

In short: use malloc.3X and OLS works.  If you use the (default)
malloc.3C, then OLS drops core.

I think your code is probably blameless.  I have had several situations
in the past where a sequence of malloc/free calls makes a program
dump core - until I learned to always use the malloc.3X library
rather than the usual malloc.3C on the SG.  SG documentation says that
their 3X external library is preferred.  I don't know why the problem
occurs, but its happened so often that whenever I get a malloc
problem I check first which library was used.  I have never tracked
down the problem to a simple code snippet that proves the flakiness
of the malloc.3C, so my comments are completely subjective.
Nevertheless, I have noticed that all source code that comes out of
SG uses malloc.3X rather than malloc.3C.
