Description Andy Lutomirski 2015-07-30 18:05:53 UTC 
Linking anything with -ffast-math adds code that runs on load that reprograms the FPU for reduced accuracy.  This applies even to shared libraries, which means that merely loading a shared library linked with -ffast-math can break programs.

Please consider disallowing any shared library linked with -ffast-math in rpmlint.

See, for example, bug 1127544.
Comment 1 Rex Dieter 2018-02-15 18:36:56 UTC 
This is more a policy-decision (ie, something for FESCo to consider), not something to be enforceable via any individual (ie, maintainer of rpmlint)
