Description of problem:
I have a simple C++ test program using OpenMP, GSL and Blitz that gives an 
internal compiler error. The error message said that I should report it here.

I have installed a self-compiled GSL in my home folder. Maybe you guys can 
test with a standard GSL/Blitz++ if that comes precompiled with RHEL5.2.

Here is the simple test program openmp_gsl_rng.cpp:

#include <blitz/array.h>
#include <gsl/gsl_rng.h>

using namespace std; using namespace blitz;

Array<double,1> R(2);

int main()
#pragma omp parallel private(R)
		const gsl_rng* r = gsl_rng_alloc(gsl_rng_mt19937);

	return 0;

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

How reproducible:

Steps to Reproduce:
1. I try to compile with:
$ g++  
openmp_gsl_rng.cpp -I/mn/anatu/cma-u3/tmac/usr/include -L/mn/anatu/cma-u3/tmac/usr/lib -lgsl -lgslcblas -fopenmp

Actual Results:
I get the following error message:

openmp_gsl_rng.cpp: In function 'int main()':
openmp_gsl_rng.cpp:0: internal compiler error: in lower_stmt, at 

Expected Results:

Additional info:
If I don't try to make the variable R private, then it compiles without 

Software versions:
GSL v1.9
Blitz++ v0.9
Comment 1 Jakub Jelinek 2008-06-26 07:50:52 EDT
Please attach preprocessed testcase.  I.e. run
g++ -E openmp_gsl_rng.cpp -I/mn/anatu/cma-u3/tmac/usr/include
-L/mn/anatu/cma-u3/tmac/usr/lib -fopenmp -o openmp_gsl_rng.ii
and attach the *.ii file.  Thanks.

Preprocessed test case

This is the output that was automatically produced by g++, and stored by it in
the file /tmp/ccWuAWvr.out.
