@targos does asan still complain when we replace memcpys with memmoves?

@RaisinTen feel free to push to my branch to try |

@addaleax What do you think we should do, then? If I land this, test-asan will be red until someone fixes the issue. |
|
@targos I think somebody needs to reproduce this locally, then figure out which zlib calls exactly are leading to this error. :/ |

Is LINK here neccessary ?

Yeah, it doesn't seem useful. /cc @mmarchini

I don't remember why LINK was necessary (to force clang linker instead of ld when linking? idk that's the only thing I can think of). We can always remove and see what happens

I do think it was more of a GitHub Actions thing and less of a gnu thing

Ok I remember now. ld would consume too much memory for ASAN to be possible on Actions, given the size of the instances available (see #32776). I'm almost sure LINK is not standard but is used by gyp. What I'm not entirely sure is if CXX being set to clang++-12 is enough. Again, someone would need to experiment (specifically looking at peak memory usage when LINK is set or not).
@addaleax This will trigger the ASAN error. Make sure Also I am confused why it's not using debug node since I pass |

Also latest clang is 13. Not sure github action bundled it yet.

GitHub runners only have clang 10,11 and 12: https://github.com/actions/virtual-environments/blob/main/images/linux/Ubuntu2004-README.md#language-and-runtime

Tried clang-13 locally, same result.

Thank you for the approvals but we still can't merge this because of the error spotted by clang-12. |

It's green now :) Can I have a new review? |

I have no idea. |

Could it be flaky? I was wondering if we should rerun CI a couple of times before landing. |
|
I force-pushed again to run with latest master (will need another review to land). We can then rerun it a couple times. |

You were right, it's flaky! |

I have issues with the default (version 11) in the PR to update V8: #39945
I hope it will fail here too and someone knows how to fix it :)
