Thanks for this pointer; that is really a scary thread.
I was a aware that too many applications demand -fwrapv nowadays, but didn't know why.

That bug discussion thread is reason to evaluate barring gcc usage in critical conditions.

Anybody can tell if the Clang developers are more reasonable if they receive that kind of problem report?

I doubt it. As several people pointed out in that bug report, the complaint was about an optimization GCC has been doing since the *early 90s*, and they were demanding extremely impolitely that it get ripped out as if it were something that had been added the previous week, and ignoring the response that it just isn't as simple as that.
