Compiling on Windows 10 Enterprise LTSC with Visual Studio Enterprise 2022 installed the code compiles and runs, but displays an error message.

Command used to compile: `cl /EHsc /W4 /showIncludes /Zi /MDd mutex_exception.cpp /link /VERBOSE > compile_log.txt 2>&1`

The compilation log output is as follows: [compile_log.txt](/uploads/bd8bd6880693d37232411218915e0cfc/compile_log.txt)

Results as follows:

```
C:\Users\Wayne Thornton\Desktop>mutex_exception.exe
locking test
main: m1 at0000008253DEFD40
main: lock: m1
t1: unlock: m at 0000008253DEFD40
D:\a\_work\1\s\src\vctools\crt\github\stl\src\mutex.cpp(152): unlock of mutex not owned by the current thread
```
