crash when parse cpp file

[lovelyzzc]

When I convert CPP files in the project, it causes a coredump. Below is the printout：

#0 0x00007ff1d7f6f503 llvm::sys::PrintStackTrace(llvm::raw_ostream&, int) (/usr/lib/libLLVM-16.so+0xe1f503)
#1 0x00007ff1d7f6c7bf llvm::sys::RunSignalHandlers() (/usr/lib/libLLVM-16.so+0xe1c7bf)

#5 0x00007ffe703c08f0 
fish: Job 1, 'insights ../src/app.cpp' terminated by signal SIGSEGV (Address boundary error)

But I can successfully convert HPP files. Below is the printout of insights --version.

cpp-insights 0.10 https://cppinsights.io (https://github.com/andreasfertig/cppinsights.git 9147b894b814a3d7dcf82ac9b16965680baffeb1)
  LLVM  Revision: 
  Clang Revision: Clang 16.0.6

I used the tag v_0.10 for compilation, and the cmake compile command is as follows.

cmake -G"Ninja" .. -DINSIGHTS_USE_SYSTEM_INCLUDES=off -DCLANG_LINK_CLANG_DYLIB=on -DLLVM_LINK_LLVM_DYLIB=on

Below is the printout of ldd.

Where should I start to troubleshoot this issue? Thanks！

Hello @lovelyzzc,

sorry for the trouble!

In your lldb printout, this line sticks out:

/home/lovelyzzc/vehicle_end/safety/src/app.cpp:1:10: fatal error: 'iostream' file not found
#include <iostream>
         ^~~~~~~~~~

C++ Insights cannot find the iostream header. This would be the starting point. The option INSIGHTS_USE_SYSTEM_INCLUDES is probably named in a hard-to-guess way. What it means is that all -I includes become -isystem with the option on and otherwise remain untouched. I'm not sure whether this option does what you're expecting.
