Errors seen in LOGS/pygoocanvas-0.14.1-6.fc17

This is a summary of errors seen when compiling with an experimental static analysis tool

Raw build logs can be seen here

Reference leaks

Code paths in which the reference count of an object is left too high, leading to memory leaks

goocanvas.override	_wrap_goo_canvas_item_model_get_child_properties	ob_refcnt of '*tuple' is 1 too high
goocanvas.override	_wrap_goo_canvas_item_get_child_properties	ob_refcnt of '*tuple' is 1 too high

Segfaults within error-handling paths

Code paths in error-handling that will lead to a segmentatation fault (e.g. under low memory conditions)

goocanvas.override	_wrap_goo_canvas_points__get_coords	calling PyList_SetItem with NULL as argument 1 (ret) at goocanvas.override:1899
goocanvas.override	_glist_to_pylist_objs	dereferencing NULL (item->ob_refcnt) at goocanvas.override:29
goocanvas.override	_glist_to_pylist_objs	calling PyList_Append with NULL as argument 1 (dest) at goocanvas.override:28

Possible reference leaks

Code paths in which the reference count of an object might too large - but in which the reference in question came from a function not known to the analyzer.

The analyzer assumes such references are new references, but if the function returns a borrowed reference instead, it's probably not a bug

goocanvas.override	_wrap_goo_canvas_item_model_get_child_properties	ob_refcnt of '*item' is 1 too high
goocanvas.override	_wrap_goo_canvas_item_get_child_properties	ob_refcnt of '*item' is 1 too high
goocanvas.c	pygoocanvas_add_constants	ob_refcnt of new ref from call through function pointer is 1 too high

Returning (PyObject*)NULL without setting an exception
