I am having serious difficulty in getting complex codes that worked well when compiled with ifc 7.1 20030922 to run when compiled withversion 8.0 or 8.1. The only indication of a problemis "Segmentation fault". I am unable to get the Fortran 8.1 build20040803Z compiler to generate code that will give any diagnostic or traceback information on run-time errors. This makes it very difficultto resolve problems.
A small test programdesigned to generate a run-time error (ie, segment fault) by allocatingtoo much memory fails but produces no diagnostic or traceback info either. But the same program compiled using 7.1 20030922 gives both.
I compile with this command: ifort -fp -traceback test.f90
I am running on a P4 under Linux 2.4.21-4.ELsmp, glibc: 2.3.2-95.3
Is there some trick to get the 8.xcompiler to produce diag/traceback info?
