for "man G++ " it is not the default, I could not find Qt makefile
to disable them, so I was a bit perplex. 
(also had integer divisions in mind, quite a difference)

I notice now that even the smallest C++ program has FPE disabled
$ cat test.cpp
#include <stdio.h>
int main() { printf("FPE test:%f\n",142.0/0.0); }
$ ./a.out
FPE test:inf

So I now use fedisableexcept(FE_ALL_EXCEPT); 
in the initialization section of qt4.pas
