Description lagoho7 2023-06-19 12:48:37 UTC

Integrating iwyu into a CMake build system using CMAKE_C_INCLUDE_WHAT_YOU_USE and CMAKE_CXX_INCLUDE_WHAT_YOU_USE fails on an assertion. It appears what you are building and what toolchain you are using are irrelevant.

The same steps work on Fedora 37.

Reproducible: Always

Steps to Reproduce:
1. Fresh install Fedora 38 Server with the "C Development Tools and Libraries" group selected.
2. Update all packages: sudo dnf upgrade --refresh
3. Install required packages: sudo dnf install cmake iwyu git libcurl-devel openssl-devel
4. Clone a CMake project (I chose Transmission arbitrarily): git clone --recurse-submodules https://github.com/transmission/transmission.git Transmission
5. cd into the project: cd Transmission/
6. Configure CMake: cmake -B build -DCMAKE_CXX_INCLUDE_WHAT_YOU_USE=include-what-you-use -DCMAKE_C_INCLUDE_WHAT_YOU_USE=include-what-you-use -DCMAKE_BUILD_TYPE=RelWithDebInfo
7. Start the build: cmake --build build
Actual Results:  
Build fails with the following error:

Error running 'include-what-you-use': /builddir/build/BUILD/include-what-you-use-0.20/iwyu.cc:3735: Assertion failed: sema.getCurScope() != nullptr

Expected Results:  
The build completes successfully with iwyu output. Tested on Fedora 37 to verify that my steps are correct.
