<LI>The default compiler distributed by Red Hat since release 7.0 is
|
|
NOT supported and not considered reliable for running a Geant4-based
|
|
application. In more than one test case, binaries produced by gcc-2.96
|
|
have shown incorrect behavior, either due to wrong order of

initialisation of static data in memory or to bugs in the system

solved in more recent versions of the compiler (3.X series).<BR>

officially released, nor supported by the GNU team itself and is not
