Why doesn't GCC show any errors on an anonymous variable?

Question

I read this question that explains how anonymous variables are invalid in C++.

But the following program compiles without any warning or errors on GCC 7.2 (even with -Wall ) - demo :

int main() {
    int (*); // anonymous variable?
}

Here, this is apparently also an integer type anonymous variable. So, why GCC does not show any errors or warnings? Is this a GCC bug?

Answer 1

There have been bugs recorded with gcc and how it detects variables for example I was using it to compile a simple program and it gave an error saying variable may be uninitialized when it have been. It is just a bug in the compiler. For example see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55985
