Well, if you had run the simple glibc testcase that I've posted above, you would have found out that your recent commits don't fix this issue. It's obvious, not only from the amount of churn, that fisolate-erroneous-paths shouldn't be enabled by default at -O2. The very few users you would like SIGSEGV to be transformed to SIGILL by the compiler should set this option explicitly.
