<pre>I stumbled across a weird error Clang 9 gives me when trying to compile the
following code snippet:
```
template<typename IndexT>
void test(double *A, IndexT k)
{
#pragma omp task depend(out: A[k])
{
// do something
}
}
int driver(double *A)
{
int k = 0;
test(A, k);
return 0;
}
```
The error:
```
$ clang++-9 test_omp_dep_template.cc -fopenmp -c
test_omp_dep_template.cc:4:34: error: expected addressable lvalue expression,
array element or array section
#pragma omp task depend(out: A[k])
~~^~
```
If I replace IndexT with int it compiles fine. I can then template the type of
A and Clang will compile fine. Compiling this with GCC works too (last time I
checked was 7.3.0).
Is this expected behavior?</pre>
