[C++-sig] what happened with this std::string parameter in boost.python

[Donnie Leen]

I made a program embedding boost.python, writting a module as following:

void write( std::string s )
{
	// do nothing
}
BOOST_PYTHON_MODULE(mym)
{
	def( "write", &write );
}


I run the python code:
import mym
s = 'hello'
mym.write(s)

it runs ok, but if i run the python code as following:
import mym
s = int.__doc__
mym.write(s)

it crashed, and it seems to crashed while boost.python try to delete the parameter s.
Can someone tell me what happened to it? Thanks first.
