Summary: lax error-checking in new-in-2.4 marshal stuff
Initial Comment:
I realise one of the points of the TYPE_STRINGREF and so on stuff
was efficiency, but:
>>> marshal.loads('R') # TYPE_STRINGREF == 'R'
Segmentation fault

While I have your attention:
>>> marshal.loads("", 1)
Segmentation fault
This is the guilty line:
if (!PyArg_ParseTuple(args, "s#|i:loads", &s, &n))
there's no pointer corresponding to the optional integer argument.
I'd just fix this, but I have too many local changes to make it easy :(

I agree, and will try to work on a patch before 2.4.2.
