So, it looks like this issue has been fixed now with current qemu 7.1 (and with current clang from unstable, 13.0.1-9). Andreas, can you verify it is fixed for you please?
I can still reproduce it with the latest qemu in sid and llvm-13/llvm-14/llvm-15/llvm-16 (but not with llvm-11). # ./alignof.sh 15 + ver=15 + cat + clang-15 -o alignof.bc -x c -emit-llvm -c alignof.c --target=aarch64-unknown-linux-gnu + lli-15 -force-interpreter alignof.bc PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
