I am analyzing a Windows dll, rpcrt4.dll, however I have also tested against other Windows binaries, including kernel drivers. You can download the binary I was using from the Microsoft Symbol Server:

https://msdl.microsoft.com/download/symbols/rpcrt4.dll/1CAF5F33115000/rpcrt4.dll

I'm running this on an M1 Mac, with Ghidra 11.0.1 and BTIGhidra version: 0.0.6.

Their fork of cwe_checker stayed far behind and kept the brittle Cspec parser, which was no longer necessary by version 10 of Ghidra as it since has a proper API to retrieve caller convention data.
