Ok, it looks like it is either a memory problem within ICU, or else a
compiler/optimizer bug.

If I build a debug version of ICU, it builds/checks/installs/runs fine
[ Although I don't have Purify, so I can't verify everything is correct ]

If I build an optimized version of ICU, it builds/installs ok, but my
program crashes when it is used (See original message).
Note though that when I do a 'make check' of the optimized build of ICU,
it crashes as follows:

% gmake check

gmake[2]: *** [check-local] Segmentation Fault (core dumped)

Note that I had been using an optimized version of ICU 2.4 on this box 
with this compiler, without any problems...
[ Although, I don't recall whether I did a 'make check' with 2.4, nor
whether it succeeded or not... ]
