It does.  It breaks IEEE compatibility and enables "unsafe"
optimizations of FP calculations.  I cannot recommend its usage in
general-purpose programs such as Emacs.

Not sure it has any relevance to the issue at hand, but I would
recommend to begin by building without that flag.

Indeed, some information about the recipe to reproduce the problem is
required to investigate this problem.
