[issue14722] Overflow in parsing 'float' parameters in PyArg_ParseTuple*

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka at gmail.com>:

In function convertsimple() in Python/getargs.c possible converting out of float range value from double to float.

Fortunately, 'f' format character is not used in CPython source code. But it can be used in the extensions.

Tests will be later.
