segfault with -O3

[manju k]

Hello,

I am getting segfault in my application if i compile it using -O3 flag , 
removing this flag during compilation resolves the problem

I am using gcc 4.1.2 on intel 64bit system.

The core file does not point to anything that I suppect of in my application.

How do I isolate if it is  gcc problem or my application problem ?
