Yes, this is unmodified llvm.   No need to build chromium.   This looks like a Wasm specific issue.   It can be reproduced by simply compiling https://github.com/emscripten-core/emscripten/blob/main/system/lib/libc/emscripten_time.c with emscripten.

To simplify this I've attached the pre-processed version of that file which you can reproduce this crash with using just: `clang -c -target wasm32-unknown-emscripten  repro.c`
