3189,Python integer/long conversion to C++ unsigned int/long is broken,anderson.lizardo@…,Dave Abrahams,"The following snippet in libs/python/src/converter/builtin_converters.cpp:

{{{
          return numeric_cast<T>(
              PyLong_Check(intermediate)
              ? PyLong_AsUnsignedLong(intermediate)
              : PyInt_AS_LONG(intermediate));

}}}

does not check if an exception was thrown by the Python/C conversion functions. Therefore, in case of error, these functions are returning -1, which is being cast to unsigned int.

Another missing check is when the Python integer value to be converted is negative. In this case, a proper exception (such as ValueError) must be thrown.",Patches,closed,Boost 1.40.0,python USE GITHUB,Boost Development Trunk,Problem,fixed,,
