[issue9980] str(float) failure

This sounds similar to issue 9215, which was due to a compiler optimization bug.  Certainly it points to something going wrong in _Py_dg_dtoa.

What platform are these results from?

Do you have minimal code that can be used to reproduce?

I'm surprised that 3.2 fixes this:  the float-to-string conversion code is pretty much identical in both 3.1 and 3.2.
