Auto-generated crash dump
Occasionally when compiling code in the PowerShell terminal in Visual Studio
Code clang-cl will crash instead of displaying the proper error message. I have
only been able to reproduce this crash in Visual Studio Code's PowerShell
terminal. This does not occur in an independent PowerShell session (could be a
Visual Studio Code problem?).
The code being compiled was a simple hello world program, intentionally
malformed using single quotes for the string rather than the proper double
quotes -> 'Hello, World!\n'
Attached is the crash backtrace, preprocessed source, and run script.
Platform: Windows 10 Pro x64 Version 1709 (Fall Creator's Update)
Visual Studio Code Insiders 1.19.0 x64 with
Latest Windows 64-bit LLVM SVN Build from <a href="https://llvm.org/builds/">https://llvm.org/builds/</a>
clang-cl options: /std:c++17 /TP /Wall /WX
Steps to reproduce (though only sometimes occurs):
1) Open broken Hello World (using 'Hello, World!\n' rather than "Hello,
World!\n" in std::cout line) source in Visual Studio Code
2) Open integrated PowerShell terminal in Visual Studio Code
3) Compile hello_world with 'clang-cl.exe /std:c++17 /TP /Wall /WX
hello_world.cpp'
Expected results:
clang-cl prints out proper error message and cleanly exits as such:
.\hello_world.cpp(5,15): error: multi-character character constant
[-Werror,-Wmultichar]
std::cout << 'Hello, World!\n';
^
.\hello_world.cpp(5,15): error: character constant too long for its type
[-Werror]
2 errors generated.
Actual results:
clang-cl crashes printing gibberish to the console and displays bug report
notice.</pre>
