Description:
As stated above, using gcc version 11.2.0-4 to compile instance of std::map with no flag specified and header bits/stdc++.h included at the front will cause an `internal compiler error` and compilation fails. However, it's observed that compiling with optimization (flag `-O2`) or sanitizers (flag `-fsanitize=undefined`) is fine, compiling with only c++ header `map` included or `map` included before `bits/stdc++.h` will not cause any error either.

Way to Reproduce:
1. write a minimal c++ source file with only `bits/stdc++.h` included and a instance of std::map
```
$ cat main.cpp
#include <bits/stdc++.h>
std::map<int, int> s;

int main() { return 0; }
```
2. compile with command `g++ main.cpp`
```
$ g++ main.cpp
during RTL pass: expand

```

output of `gcc -v main.cpp` is attached as verbose_output_gcc.txt.

The error will trigger as long as `bits/stdc++.h` is included first.
```
#include <bits/stdc++.h>
#include <map>
std::map<int, int> s;

int main() { return 0; }
```
code above will trigger the error, but source codes below will all compile just file.
```
#include <map>
#include <bits/stdc++.h>
std::map<int, int> s;

int main() { return 0; }
```
```
#include <map>
std::map<int, int> s;

int main() { return 0; }
```
