          Issue ID: 23055
           Summary: importC: using compound-literal array as pointer in
                    CTFE gives 'dereference of invalid pointer'
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: CTFE, ImportC
          Severity: minor
          Priority: P1
         Component: dmd

int fn()
{
        int *p = (int[1]){0};
        *p = 0;
        return *p;
}
_Static_assert(fn() == 0, "");
int main()
{
        return fn();
}

test.c(4): Error: dereference of invalid pointer `[0]`
test.c(7):        called from here: `fn()`
test.c(7):        while evaluating: `static assert(fn() == 0)`

it works outside CTFE
