The program directly crashed with a floating point exception and gives the message "Fortran runtime warning: IEEE 'denormal number' exception not supported" with an without the compiler option -ffpe-trap. The same program functions well if compiled with the intell fortran compiler ifort. OS : linux (i686) release 2.6.16.54-0.2.5-smp I tried to find the error in the debugger kdbg, but before the first executable statement was passed the program stopped with the floating point error. Can someone tell what is the matter, and how it can be solved. We want to use the gfortran compiler when it works well. -- Summary: Floating point exception Product: gcc Version: 4.1.2 Status: UNCONFIRMED Severity: blocker Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: martin dot weterings at rws dot nl http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38810
