application crash if compiled with -fopenmp

[Daniel Franke]

Hi all.

Somewhat strange problem: I have a large source file (1.2MB, 32kloc)
that compiles (and works) fine. Compiling the same source, that does
not yet contain any OMP statements, with -fopenmp, it crashes
immediately on runtime (bt below). This holds for gfortran-svn
20080107 on i686 and x86_64. Using gfortran-4.2 20080107, it seems to
work as expected. Of course, the same does not happen with a two-line
hello-world program. I'll try to cut the large file down as soon as I
find time to do so ...

Has anyone seen this before?
