Setting a C-structure from Python

[Benoit Dupire]

I think I find out where the bug was.
Thanks Armin !

Why this C extension didn't work ?

Simply because the  "example"  pointer  points to memory owned by
string_from_python
it point to internal data which is actually part of the string object.
When I "decref "   string_from_python, its reference counter becomes 0, and
the string object is deleted.
So  "example" points to something wrong in memory.


thank you again
Benoit.
