--- Comment #2 from Aldy Hernandez <aldyh at gcc dot gnu.org> ---
This is interesting.=20=20

quux() was analyzed and a global range was set that included the possibilit=
y of
+NAN, but when it was inlined into bar(), the assert making sure no NANs cr=
ept
in for -ffinite-math-only failed.

So the inlined function had a NAN, but the function where it was being inli=
ned
into has -ffinite-math-only.=
