[New-bugs-announce] [issue22462] Modules/pyexpat.c violates PEP 384

[Mark Shannon]

New submission from Mark Shannon:

Modules/pyexpat.c includes some archaic code to create temporary frames
so that, in even of an exception being raised, expat appears in the traceback.

The way this is implemented is a problem for three reasons:

1. It violates PEP 384.
2. It  is incorrect, see http://bugs.python.org/issue6359.
3. It is inefficient, as a frame is generated for each call, regardless of whether an exception is raised or not.

The attached patch fixes these issues.
