@stmontgomery Yes, applying this diff on top of 47b127f1c98a9f4ff593288c7ee0c6618a912e6b allows the build to complete ```diff diff --git a/Sources/TestingMacros/CMakeLists.txt b/Sources/TestingMacros/CMakeLists.txt index c916204..bb55f09 100644 --- a/Sources/TestingMacros/CMakeLists.txt +++ b/Sources/TestingMacros/CMakeLists.txt @@ -31,8 +31,8 @@...

I did see some interesting compiler warnings (visible in my gist in the initial post) about experimental features not being enabled as expected, so it could be some CMake flag...

Nah, still seeing errors with CC=good-clang and all of the ASAN_OPTIONS and UBSAN_OPTIONS set. We'll see if CI comes up with the same answer after I push this up :sweat_smile:

Having to set CC and CXX also means that this no longer becomes transparent for command line vs IDE tooling, and we'll need to setup the IDEs to export CC...
