While attempting to generate AST with clang 15.0.7 with code that includes headers from MSVC 17.3.5, clang crashes.
Attached is a zip file containing:
1. main.cpp, a small program that can generate the clang crash
2. build.bat, shows the command line used on my system to generate the crash
3. err, output generated from running build.bat on my system
4. msvc-17.3.5, copies of the entire source files from which main.cpp was pieced together, included here for context (if necessary)
Below is the stack dump generated from the crash, pasted here for convenience:
```
Stack dump:
0. Program arguments: "c:\\Program Files\\LLVM\\15.0.7\\bin\\clang.exe" -v -c -Xclang -ast-dump=json main.cpp
1. <eof> parser at end of file
2. main.cpp:55:27: Mangling declaration '_Is_member_object_pointer<type-parameter-0-0 type-parameter-0-1::*>::value'
Exception Code: 0xC0000005
