[cfe-dev] Clang-tidy crashes when string reference used as parameter

[Jonas Toth via cfe-dev]

Hi Stuart,

i can reproduce the issue, but it is not within clang-tidy, directly but
in the CSA. The following invocation is the only invocation that results
in the segfault.

~/opt/llvm/build/bin/clang-tidy
-checks=-*,clang-analyzer-cplusplus.InnerPointer clang-tidy-bug.cpp --

The bug is reported here: https://bugs.llvm.org/show_bug.cgi?id=38827

Best, Jonas
