I've found compiler bugs before, but this is the first compiler-compiler bug I've ever seen – incredible stuff:

https://issues.chromium.org/issues/336399264

Screenshot of comment #89 from link: On my M1 Macbook at Chrome revision e8ce89ebb49e7 I ran: ./tools/clang/scripts/build.py --bootstrap --disable-asserts (Notice no --run-tests because I seem to remember I tried this before and it fails the tests. I didn't repro that today though.) The resulting aarch64 compiler does evidence the bug compiling repro.cc. My current hypothesis is that the bug compiling repro.cc shows up when running aarch64 Clang @ ab037c4f as compiled by Clang @ ab037c4f running on any architecture. Paging Ken Thompson.
