Regarding the w3m crashes on aarch64, I've noticed that dropping the optimization level from -O2 to -O1 for w3m stabilizes it for me. However, I don't see the connection with how this interacts with boehm-gc. It looks like clang -O2 adds -vectorize-loops and -vectorize-slp which seem unrelated to things that would affect boehm-gc. -Kurt
