with llvm/clang 20.1.8 (with Cygwin-related patches backported) I am able to build llvm, clang, and lld with clang and am able to strip the resulting executables.
with llvm/clang 21.1.0-rc1 I am able to build with clang but when I attempt to strip executables with llvm-strip I get an error `unexpected associative section index` (#53433) and when I attempt to strip executables with binutils 2.44 strip I get an executable that crashes on startup (I was able to catch it once during pseudo-relocations).
I don't have much detail yet, but I wanted to get this recorded and have a place to track the investigation. I imagine my next step would be to set up a git bisect operation to try to figure out what's going on. I don't have any ideas on how to reduce a test case, just that lld.exe and clang.exe are bugged, but simple C and C++ hello world executables are not.
