[C++-sig] boost.python: no overflow checking for unsigned int parameters ?

[Ralf W. Grosse-Kunstleve]

If you send me a patch (against the boost trunk) I'll test it and check it in.
Probably, the file to be changed is
  boost/libs/python/src/converter/builtin_converters.cpp
I'd try working with
  boost/numeric/conversion/cast.hpp

Hi,

I noticed that boost.python silently accepts negative (or too long)
integers for constructor/methods that have "unsigned int" parameters.
(signed) "int" arguments seem to be handled just fine. Is it possible
to tell boost.python to check for overflow and raise an exception just
like it happens to int parameters ?

BTW, I'm using boost1.38.

See test case below (save it as "mymodule.cpp"), "MyClass1" uses int
parameters, "MyClass2" uses unsigned int:
