[Python-checkins] CVS: python/dist/src/Include frameobject.h,2.32,2.33

[Tim Peters]

Update of /cvsroot/python/python/dist/src/Include
In directory usw-pr-cvs1:/tmp/cvs-serv4915/python/dist/src/Include

Modified Files:
	frameobject.h 
Log Message:
PyFrameObject:  rename f_stackbottom to f_stacktop, since it points to
the next free valuestack slot, not to the base (in America, stacks push
and pop at the top -- they mutate at the bottom in Australia <winK>).
eval_frame():  assert that f_stacktop isn't NULL upon entry.
frame_delloc():  avoid ordered pointer comparisons involving f_stacktop
when f_stacktop is NULL.
