Comment (by sjamaan):

 OK, that helps, after installing clang 19 I'm getting an illegal
 instruction straight away on the first test, with those options you
 mention.

 How can I get the full runtime (like you mentioned above) in order to get
 better diagnostics? I tried adding `-fsanitize=undefined`, but that just
 results in boatloads of linker errors like the following random snapshot
 from the output:

 {{{
 c-backend.c:(.text+0xa78ec): undefined reference to
 `__ubsan_handle_function_type_mismatch_abort'
 /nix/store/vk4mlknqk9yjbqa68a7rvpfxfdw3rad7-binutils-2.43.1/bin/ld: user-
 pass.o: in function `C_user_2dpass_toplevel':
 user-pass.c:(.text+0xf5): undefined reference to
 `__ubsan_handle_builtin_unreachable'
 }}}

 This happens both on NixOS and Debian (after struggling for a while
 figuring out I needed `libclang-rt-19-dev` to get
 `libclang_rt.ubsan_standalone.a`). Is there some magic option I need to
 pass to make it work?
