Optimization Failure?

[Michael D. Berger & Rosalie A. Clavez]

Using:
   gcc 2.95.3-5
   cygwin 2.78.2.9
   WIN2000Prof
I have code that works when compiled with -O2 but fails during
execution when compiled with -O3. The failure is similar to one
seen with known memory abuse.  The code makes extensive use of
templates (Borland model) and inline.

Should I look for a problem in my code, or is it more likely
a compiler problem?  

If it is a compiler problem, will a later available version help?

Thanks in advance for your help.
Mike.
