We use in our project some third party libraries compiled with gcc343 (RH9). After we moved to CentOS with gcc411, we compiled our project files with the gcc411 and linked with third party libraries. In some cases our executable has abnormally terminated. Only when some of the libraries were compiled with gcc411, the abnormal termination was disappeared.
Assuming that both compilers are binary compatible, It is possible to
link two modules compiled in different compiler version (gcc343,
gcc411). But in practice, it is not the case.


You'll have trouble with C++, whereas C should probably be okay.  Which
was it?
