I'm trying to use Fortran OpenMP on AMD64 with static linking:

simple.f90:

program launch
!$OMP PARALLEL
  write (*,*) "foo"
!$OMP END PARALLEL
end program launch

$ gfortran-4.2 simple.f90 -fopenmp -static -lgomp
$ ./a.out
zsh: segmentation fault (core dumped)  ./a.out
¤ gfortran-4.2 simple.f90  -fopenmp -lgomp        
¤ ./a.out                                 
 foo
 foo
 foo
 foo
¤ gfortran-4.2 simple.f90  -static -lgomp         
¤ ./a.out                                
 foo

This happens with fortran and on amd64 only, C or i386 work fine, so
it looks like this is the combination of fortran+openmp+static+amd64.

Ah, though gdb fails when directly running a.out, it works via the
core file:

(gdb) bt
#0  0x0000000000000000 in ?? ()
#1  0x0000000000405dd6 in get_external_unit ()
#2  0x0000000000404abd in data_transfer_init ()
#3  0x00000000004002f8 in MAIN__.omp_fn.0 (.omp_data_i=0x0) at simple.f90:19
#4  0x00000000004002aa in MAIN__ () at simple.f90:16

Note: line 16 of the program is "program launch", and line 19 of the program is
the write call

What glibc version are you using?

I tried to upgrade to glibc 2.5 and gcc svn snapshot of 20070105, with same
result.

Static linking with -lpthread (which -fopenmp uses) is not supported in
glibc/NPTL.  You can probably make it working by adding
-Wl,--whole-archive -lpthread -Wl,--no-whole-archive
to the command line, but there are no guarantees it will work.

Anyway, this is not a GCC bug but GLIBC feature.
