After thinking about it a bit more I am OK with Vinay's proposal. Attached is
an updated patch.
Also, I also noticed that the 'struct' module has the same problem:
big_int = int(sys.float_info.max) * 2
struct.pack('d', big_int)

That is a good question. While it is true that errors other than
'PyExc_OverflowError', will be mapped onto a 'TypeError' I don't think that is
a bad thing. Any errors that come out of 'PyFloat_AsDouble' should be handled
on a case-by-case

While the patch might improve over the current situation, doesn't it
potentially mask other errors which might be raised by PyFloat_AsDouble()?
Why not just
x = PyFloat_AsDouble(value);
if (PyErr_Occurred())
return NULL;
which would

This problem still occurs in the main development branch. I think the
'PyErr_ExceptionMatches' check that Pauli suggested will work. The same
problem exist for 'c_float', 'c_double', and 'c_longdouble'.
Attached is a patch that fixes the

I'm a newbie what it comes to Python's C-sources, so please do not

I fetched the sources 'svn checkout

studied the issue, and my best guess is that

If d_set makes the conversion, py3k does the same thing:
http://svn.python.org/projects/python/branches/py3k/Modules/_ctypes/cfield.c
It has a function d_set_sw, which might have same issues as well. The
same function can be found from 2.6

Thanks for your report. Unfortunately, 2.6 and 3.1 are stable releases, they
only get security and documentation fixes. 2.7 is nearly in the same state,
since it’s at the release candidate stage. Can you check if your bug still
applies to 3.2

2.6 does receive bug fixes. 2.5 is the version in security fix only mode.
