So that it can call Python's import function.
Seems to be thrashing around a bit.

Hmm, looks simple enough.
Output from gdb:
(gdb) boost::python::import (name=@0x7fff5fbff690) at libs/python/src/import.cpp:19 19 char *n = python::extract
(name); This is where the bug is (in Boost.Python). One should never try to extract a pointer to non-const char from a str. Could you try the enclosed patch and see if your problem is fixed?
Yes, applying this patch to the 1.43 release fixes the problem. Dave, can this patch be applied to version control head if it has not been already? -- Brian Ray
