"import re: re.finditer("a", {})" crash on Python 2.x (tested with svn 
trunk) because of an invalid use of PyObject_NEW/PyObject_DEL. The 
error is in pattern_scanner(), in block "if (!string) { ... }".
 - scanner_dealloc() calls Py_DECREF(self->pattern); whereas pattern 
attribute is not initialized
 - scanner_dealloc() calls PyObject_DEL(self); whereas 
scanner_dealloc() is already the destructor of self object!

I wrote a patch to fix these errors. Please review my patch, I don't 
know C API very well.

I also patched _compile(): replace PyObject_DEL() by Py_DECREF(). Is 
it really needed?
