Problem with g++ in linux

[Roger Z Rios]

I have a C++ code that compiles and runs perfectly under
the Sun CC compiler Solaris 7.  I am now trying
to run my code using Linux Suse gnu g++ 3.3.1.  Compilation
goes ok, but then, when running, I get a lot of
segmentation fault errors,  am I missing any flag??
The code is supposed to be standard C++.

Thanks for any input,
