Description Hugh Merz 2006-08-18 21:46:13 UTC 
Description of problem:

Compiling the attached OpenMP fortran code with gfortran causes an ICE when
specifying `-fopenmp` and any of `-O1`,`-O2` or `-O3`.  

Version-Release number of selected component (if applicable):

gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)

How reproducible:

Fails to compile every time.

Steps to Reproduce:
1.copy pmfast_shmem.F90 and fftw3.f to $PWD
2.gfortran -g -O3 -DFFTW_ONLY -c -fopenmp pmfast_shmem.F90
  
Actual results:

>gfortran -g -O3 -DFFTW_ONLY -c -fopenmp pmfast_shmem.F90
pmfast_shmem.F90: In function 'density_proj':
pmfast_shmem.F90:1955: internal compiler error: in
initialize_inlined_parameters, at tree-inline.c:1158

Expected results:

Code should compile.  It works fine if `-fopenmp` is omitted, or if
optimizations are set to `-O0`.  Also works with other fortran OpenMP compilers.
