This is usually a problem that is not using llvm-ar. I cannot reproduce this problem with either llvm 10.0 or TOT version. Which linker version are you using? You can also try pass "-Wl,-debug_snapshot" to the command where the error produces and then locate the "*.ld-snapshot" in /tmp directory and attach that as a reproducer.

David, Thanks for looking into this. I did a small reproduction on my machine outside of my build system. So here is how to reproduce: Download https://downloads.xiph.org/releases/ogg/libogg-1.3.4.tar.xz Download llvm-10.0.1 macOS binary export PATH=<path to llvm/bin>:$PATH export SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk untar
