>This appears to be caused by using the -Ofast compiler flag. Using -O3 removes the issue.
-Ofast isn't supposed to just throw all semantics out of the window; it trades some accuracy and finer points of FP for speed.
It is surprising that using -Ofast makes the compiler incapable of computing sqrt(5.0). For all we know, it could be a bug in Emacs, or in the compiler (whose authors would then very much like to hear about it).
What C compiler and version did you use?
