Actually using "Pentium Pro and above" code generation fixed a problem when
using VC++ 7.0, not VC++ 6.0 (we never had any problems with 6.0 sp4, in
this area anyway).

It might not be service pack 5 that's the problem -- the processor pack is
known to generate bad code under some circumstances.

Also, are you using full (/O2) optimizations in your apps?  Dinkumware (who
wrote the VC++ 6.0 STL, so should know) say that the only safe set of VC++
6.0 optimizations is...

        " /Oityb1, which we use to build the library. That's the safest
combination we know of. "

I actually did read this before posting. I have been trying to debug the
whole situation for the past 2 days. I am going to try what Chris Newcombe
suggested and switch to Pentium pro+ processor support and see if that fixes
anything.

If that still does not work I will install VC++ 6 on a machine with SP4 and
test that.
