Internal compiler error: in estimate_move_cost, at tree-inline.cc:4249

[lpsinger]

The following code:

// test.c
void crash_compiler(const int *dimensions)
{
    const int n = dimensions[0];
	const int m = dimensions[1];

    #pragma omp parallel
    {
        const float data[m];
    }
}

produces the following internal compiler error when compiled with OpenMP enabled:

$ gcc -fopenmp -c test.c 
during GIMPLE pass: local-fnsummary
test.c: In function 'crash_compiler':
test.c:11:1: internal compiler error: in estimate_move_cost, at tree-inline.cc:4249
