<pre>Clang fails to attempt parsing a /statement/ as an /expression-statement/ when
it encounters a comma (or an assignment operator) in the potential array bound
in its attempt to parse the /statement/ as a /declaration-statement/.
### SOURCE:
void foo(int *x, unsigned idx) {
int(x[0, idx]);
}
### INVOCATION:
clang++ -cc1 -fsyntax-only subscriptvex.cc
### ACTUAL OUTPUT:
subscriptvex.cc:2:11: error: expected ']'
int(x[0, idx]);
^
subscriptvex.cc:2:9: note: to match this '['
int(x[0, idx]);
^
subscriptvex.cc:2:8: error: redefinition of 'x' with a different type: 'int
([0]' vs 'int *'
int(x[0, idx]);
^
subscriptvex.cc:1:15: note: previous definition is here
void foo(int *x, unsigned idx) {
^
2 errors generated.
### EXPECTED OUTPUT:
Clean compile.</pre>
