True. I have seen a few of those too, but not as many
as the uninitialized floats. But if you then go look
at the code, most of the time the authors never
intended that divide by zero to happen to begin with
anyway and the zero denominator is usually traced back
to a lurking bug.
That being said, there are certain classes of apps
that depend on ieee conformance. But those apps 99.9%
of the time know why they need such conformance and
why they need to use the "-mieee" option.
Unfortunately (for us), most apps that use it are only
using it to work around crashes that happen without
it, and no one really knows why for sure.
