// Description:

//
// -----------------------------------------------------------------------
// This global method should be used on LINUX/gcc or MacOS/clang platforms
// for activating NaN detection and FPE signals, and forcing abortion of
// the application at the time these are detected.
// Meant to be used for debug purposes, can be activated by compiling the
// "run" module with the flag G4FPE_DEBUG set in the environment.
