Clang-20 keeps crashing on my system

I am using Clang-20 with gcc-13 for libstdc++, but while compiling LLVM with it, the compiler keeps on crashing randomly with no real error message. If I rerun the same thing, it will pass and then fail randomly at some other compilation. Is this some issue with my machine or some resource constraint that triggers OOM?

```

Start by reproducing the LLVM build with clang++-20 and the linker command shown for bin/llvm-gsymutil. Inspect the /usr/bin/ld.lld stack dump, especially LinkerDriver::link, and determine whether repeated failures correlate with resource exhaustion or a linker crash; done means identifying a reproducible cause or a sufficiently reduced reproduction.
