Issue #24731 : Fixed crash on converting objects with special methods
...
__str__, __trunc__, and __float__ returning instances of subclasses of
str, long, and float to subclasses of str, long, and float correspondingly.

Issue #25678 : Copy buffer objects to null-terminated strings.
...
Avoid buffer overreads when int(), long(), float(), and compile()
are passed buffer objects. Similar code is removed from the
complex() constructor, where it was not reachable.
Patch backported from issue #24802 by Eryk Sun.

I finally got the time to update and merge Mark's and my trunk-math branch. The patch is collaborated work of Mark Dickinson and me. It was mostly done a few months ago. The patch fixes a lot of loose ends and edge cases related to operations with NaN, INF, very small values and complex math.
...
The patch also adds acosh, asinh, atanh, log1p and copysign to all platforms. Finally it fixes differences between platforms like different results or exceptions for edge cases. Have fun :)

The new float repr causes too much trouble and pain. I'm disabling the feature until we have sorted out the issues on all machines. 64bit machines seem to have issues and Guido has reported even worse.

Guido: It's pretty bad actually -- repr(1e5) comes out as '1.0'... Ditto for
repr(1eN) for most N... Both in 2.6 and in 3.0...

This is my patch:
...
[ 1181301 ] make float packing copy bytes when they can
which hasn't been reviewed, despite numerous threats to check it in
anyway if noone reviews it. Please read the diff on the checkin list,
at least!
The basic idea is to examine the bytes of some 'probe values' to see if
the current platform is a IEEE 754-ish platform, and if so
_PyFloat_{Pack,Unpack}{4,8} just copy bytes around.
The rest is hair for testing, and tests.
