Extended Description

The code linked to in the following comment (using Boost.Spirit.X3, so I can't seem to compress it beyond 1.8MB) causes the following error followed by a crash:

I couldn't upload to gist or pastebin so I put it on my cloud storage: preprocessed source cpp: https://rubenvb.stackstorage.com/s/6ydNjoKPNYb1X54 run script: https://rubenvb.stackstorage.com/s/eUSD4wqzArgd8Pi memory dump: https://rubenvb.stackstorage.com/s/2D7s8a7pIHTFhXY

All of these files were generated by Clang itself when it crashed.

If I can/need to upload somewhere else, let me know.

The symbol in question is one defined in Boost Spirit. This only seems to be an issue in the "clang-cl" version, MinGW-w64 Clang on Windows works just fine it seems.

This issue seems to be somewhat related to:

All links are dead. @rubenvb do you still have those files around?

rubenvb commented 1 year ago

@Endilll I have just tried to rebuild the same code with LLVM/Clang 15.0.6 (installed through VS2022) and it builds fine. I'm quite sure this issue has been fixed since I reported it.
