I naively tried to build something with -fsanitize=address using llvm-4.0 port available on OpenBSD 6.1-amd64. I was immediately greeted with: clang-4.0: error: unsupported option '-fsanitize=address' for target 'amd64-unknown-openbsd6.1'
How deep a rat hole does one have to go to port ASan to a new flavour of BSD? Is OpenBSD going to be particularly painful with its special malloc and advanced ASLR? Is anybody working on this? Thanks Greg
