openmp directive wrongly considered incorrect

[Stéphane Zuckerman]

When compiling some code using the "default(none)" clause, I get the following gcc error:

szuckerm@evans201g:~/Programming/C/OpenMP$ gcc -fopenmp -c -std=c99 minimal.c
minimal.c: In function ‘minimal_omp’:
minimal.c:6:46: error: ‘B’ is predetermined ‘shared’ for ‘shared’
minimal.c:6:46: error: ‘A’ is predetermined ‘shared’ for ‘shared’

This happens at the parsing stage, so I don't think it is a libgomp error.

Here is the code:
/* A and B are shared/read only, but with default(none) I should have to actually specify it explicitly */

void
minimal_omp(double const * const A, double const * const B)
{
    #pragma omp parallel default(none) shared(A,B)
    {
        double lsum = A[0] * B[0];
    }
}
