I guess i can post a workaround here

This code doesnt compile:
"""
int main() {
        ({
                unsigned int len = 10;
                struct {
                        int array[len];
                } new_object;
                new_object;
        });
}
"""

But this does:

"""
unsigned int foo(unsigned int rv) { return rv; }

int main() {
        ({
                unsigned int len = 10;
                struct {
                        int array[foo(len)];
                } new_object;
                new_object;
        });
}
"""
