--- Comment #3 from Valentine <v at vsamko dot com> ---
I'm having the same problem with gcc 7.2. Clang handles this correctly.

constexpr int gcc_bug() {
    for (unsigned int i = 0; i != 1; ++i) {
        continue;
        int q = 0;
        while (q == -1) {}
    }
    return 0;
}

int main() {
    constexpr int x = gcc_bug();
}
