As a general rule of thumb I would suggest the following.... If you get a warning, that we promote to an error, it is likely that it will be easy to fix with a cast. The reason is a lot of the work happens with Visual Studio but we have warning cranked way up. Both gcc and clang are more pedantic than Visual Studio. I think Visual Studio choses to let some things slide due to the need to support historical code. I don't even think the Windows headers would compile at the warning == error level we have set in the edk2 project.
If you get a crash or arguments look bad it could be bad usage of EFIAPI. As I pointed out since on non GCC compilers it is a no-op and misuse does not cause compiler warnings it is a possible cause of GCC only bugs. It is also possible that just throwing a new compiler at the code will find latent bugs, so you could be finding a bug that just has never manifested itself. If you are having trouble getting debugging working it is probably a good idea to ask folks on the list for help and info about your toolchain. Also remember the EADK (StdLib) does not currently support as many compilers as the core edk2 code. Daryl is working on it, and I'm sure he is glad to get help. For example see if you can fix the warning with a cast, or see if you can find the missing or extra EFIAPI and file a bug report or post to the list. Thanks for the help.
