Default Bug#493490: gfortran segfaults with openmp

Package: gfortran
Version: 4:4.3.1-2
Severity: normal


A program compiled with the option -fopenmp does not run. It simply
gives a segmentation fault. If the program is compiled without the
-fopenmp option, it runs without errors.
The program (called prov.f90) is the following

PROGRAM ELMAT
IMPLICIT DOUBLE PRECISION (A-H,O-Z)
PARAMETER(NA=26,NB=26,NFV=98)
DIMENSION SSCFA(NA,NB+NFV),HSCFA(NA,NB+NFV),GSCFA(NA,NB+NFV, NA,NB)
SODET=1.D-1
SSCFA=0
HSCFA=0
GSCFA=0
STOP
END

It was compiled with the command: gfortran -O0 -fopenmp prov.f90
This fact makes the OPENMP unusable on my system.
Thank you. Best regards

Stefano
