It looks as if your toolchain doesn't automatically link anything that provides the exception ABI. On most *NIX systems this comes from something called (which, on FreeBSD, is actually LLVM's compiler-rt - on some platforms it's installed as such). What happens when you compile a C program that uses -fexceptions and __attribute__((cleanup)) on OpenBSD? Does it link something that provides these symbols?
