Sorry, sorry! Ignore my previous two commits. I mixed up the version

of python with which I tried running the crashers. They don't crash
the current HEAD.

I am not too sure why, but you can surely find out by gdb'ing a bit...

Fix a crasher where Python code managed to infinitely recurse in C code without
...
ever going back out to Python code in PyObject_Call(). Required introducing a
static RuntimeError instance so that normalizing an exception there is no
reliance on a recursive call that would put the exception system over the
recursion check itself.

Add checking for a number of metaclass error conditions.
...
We add some new rules that are required for preserving internal
invariants of types.
1. If type (or a subclass of type) appears in bases, it must appear
before any non-type bases. If a non-type base (like a regular
new-style class) occurred first, it could trick type into
allocating the new class an __dict__ which must be impossible.
2. There are several checks that are made of bases when creating a
type. Those checks are now repeated when assigning to __bases__.
We also add the restriction that assignment to __bases__ may not
change the metaclass of the type.
Add new tests for these cases and for a few other oddball errors that
were no previously tested. Remove a crasher test that was fixed.
Also some internal refactoring: Extract the code to find the most
derived metaclass of a type and its bases. It is now needed in two
places. Rewrite the TypeError checks in test_descr to use doctest.
The tests now clearly show what exception they expect to see.

SF bug #1296433 (Expat bug #1515266 ): Unchecked calls to character data
...
handler would cause a segfault. This merges in Expat's lib/xmlparse.c
revisions 1.154 and 1.155, which fix this and a closely related problem
(the later does not affect Python).
Moved the crasher test to the tests for xml.parsers.expat.

If a classic class defined a __coerce__() method that just returned its two
...
arguments in reverse, the interpreter would infinitely recourse trying to get a
coercion that worked. So put in a recursion check after a coercion is made and
the next call to attempt to use the coerced values.
Fixes bug #992017 and closes crashers/coerce.py .

An object with __call__ as an attribute, when called, will have that attribute checked for __call__ itself, and will continue to look until it finds an object without the attribute. This can lead to an infinite recursion.

As I threatened on python-dev, add a directory which contains all known
...
bugs which cause the interpreter to crash. I'm sure we can find a few
more. Many missing bugs deal with variations on unchecked infinite recursion
(like coerce.py).
