Greetings,
the clang-check built from main in GitHub cloned yesterday, fails the check of the same file that was mentioned in #104800.
The command, from the build/bin directory was
Ě€devel/clang/llvm-project/build/bin>
% ./clang-check --analyze -p /home/rusconi/devel/xpertmass/build-area/unix/compile_commands.json /home/rusconi/devel/xpertmass/development/src/XpertMass/PolChemDef.cpp `
This is the output

I could not find a way to create preprocessed source files, but the ones from #104800 might help ?
I'd be eager to provide any information aimed at solving this issue (maybe the full backtrace or the output from strace).
Most sincerely,
Filippo Rusconi
