Close it and "hope" it was never mentioned. There is no bug. The pointer
dereference is valid. The error message is the same as for
struct { int i; } foo; void bar(void) { if (foo) baz(); }
The test would be better written as `if (foo != NULL)'. Then it is obvious
that there is a binary operator `!='. Structs are invalid operands for
'!='.
