When they run on Linux mono-processor or Solaris machines, there is no
problem !

Are the Solaris machines mono- or multi-processors? If the former, there's likely an error in your SW that assumes the semantics of a mono-processor system; if the latter, there's probably an error in the Linux GNAT version you're using.

What version of GNAT are you using? I know that the SGI Ada compiler, which is supplied by AdaCore and invoked by "gnatmake", worked fine on SGI multi-processor systems in 2000.
