Doesn't reproduce for me on 18.1.0 and trunk.

Endilll commented 2 months ago

@bluefish43 Can you check how 18.1.5 and trunk work for you? If it still crashes on 18.1.5, we need to identify an offending patch in a timely manner if we want this to be fixed in 18.1.6 (which is going to be the last 18 release).

I would but I do not know exactly what "trunk" is in this case.

Clang built from a recent commit in main branch.

Okay so it has been building for more than one hour now, and is still at 34%, but I will try to build it as soon as it finishes building.

I am sorry but trying to build clang from llvm-project's main branch resulted in crashing my computer. I don't think I will be able to build it myself, as it seems to be a performance-heavy task.

One of the typical bottlenecks while building Clang is RAM usage during linking. We have LLVM_PARALLEL_LINK_JOBS CMake variable just for that. You can also try nightly builds from https://apt.llvm.org if you're on Linux.
