Compiler options:
```
/EHs-c- /GR- /std:c++20 /permissive- -Wno-deprecated-declarations -msse4.2 /Zc:tlsGuards- /GS- /JMC- -Wno-unused-parameter -Wno-microsoft-enum-forward-reference -Wno-inconsistent-dllimport /clang:-fno-threadsafe-statics /clang:-fno-unwind-tables /clang:-fno-asynchronous-unwind-tables -Wno-pragma-pack -Wno-unused-local-typedef -Wno-unknown-pragmas /fp:except-
```
Unfortunately i can't reproduce this in the empty project, i assume that's it's caused by the symbol override like this:
```
void* __cdecl malloc(size_t size) {
return 0;
}
decltype(&malloc) __imp_malloc = &malloc;
```
