The backtrace of the following program is not the same on POSIX and Windows platforms:
```cpp
#include <functional>
#include <iostream>
static void target() {
int a = 0; // break here
}
int main() {
std::function<void()> fn = [] { target(); };
fn();
return 0;
}
```
On POSIX:
```
* thread #1, queue = 'com.apple.main-thread', stop reason = breakpoint 1.1
* frame #0: 0x0000000100001460 skipped_frames`target() at skipped_frames.cpp:5:7
frame #1: 0x0000000100001450 skipped_frames`main::$_0::operator()(this=0x000000016fdfe940) const at skipped_frames.cpp:9:35
frame #8: 0x000000010000062c skipped_frames`std::__1::function<void ()>::operator()(this= Lambda in File skipped_frames.cpp at Line 9) const at function.h:995:10
frame #9: 0x000000010000056c skipped_frames`main at skipped_frames.cpp:10:3
frame #10: 0x000000018cc41d54 dyld`start + 7184
```
On Windows:
```
* thread #1, stop reason = breakpoint 1.1
* frame #0: 0x00007ff7f3c37811 hidden_frames.exe`static void target() at hidden_frames.cpp:5

frame #8: 0x00007ffd02a4c53c ntdll.dll`RtlUserThreadStart + 44
```
On Windows, none of the frames are hidden.
