$ ruby -v -e '1 & 1.2'
ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin14]
-e:1: warning: possibly useless use of & in void context
-e:1:in `&': 1.2 can't be coerced into Float (TypeError)
	from -e:1:in `<main>'
~~~

It's telling me it couldn't coerce a Float into a Float, when it probably means into an Integer (or maybe Fixnum?).

I looked at the C, but couldn't see where the problem is. coerce_failed seems to use the correct value to get the class for the error so must be something before there.
