If you are asking the OS to report writes into the "old generation" by write-protecting pages, the OS has no way to do so but raising a SIGSEGV (or similar exception under Mac OS/Mach and Windows).

Again, that's not a real problem. When a SIGSEGV is really an error and is turned into a SIGABRT, the backtrace is totally recognizable and you get the fault address in the backtrace.
