This warning is enabled when source code using the macros ``INFINITY`` or
``NAN``
is compiled with floating-point options preventing these two values. This can
lead to undefined behavior. Check the order of command line arguments that
modify
this behavior, such as ``-ffast-math``, ``-fhonor-infinities``, and
``-fhonor-nans`` (etc), as
well as ``#pragma`` directives if this diagnostic is generated unexpectedly.
