Running:

make VERBOSE=1 -j6 check-tidy-misra

Fails with:

********************
Testing Time: 0.41s
********************
Failing Tests (1):
    clang-tidy-misra unit tests :: cpp2008/18-4-1.cpp

  Expected Passes    : 43

Testing the command by hand just results in a segfault:

./clang-tidy /tmp/build2/tools/clang/tools/extra/clang-tidy/misra/test/cpp2008/Output/18-4-1.cpp.tmp.cpp --checks=misra-cpp2008-18-4-1 -- --std=c++11

Thanks for the report!

Which operating system, compiler and build type are you using?

dapperfu commented

Ubuntu 18.04. Fails on both Ninja and GNUMake.

Release or debug build?

ps: Will not be around for almost one week. Gonna investigate after.

dapperfu commented

Release. Mostly following the build script.

And I'm in no rush.

It looks like I am able to reproduce the crash with LLVM_USE_SANITIZER set to Address. Will work on it as "soon" as I got time.
