[Pyrex] Subclassing an extension type from a built-in

[Michael Hordijk]

    So I've been reading the docs, googling, and reading these archives
on GMane (which has given me a bunch of ideas, thanks!).  What I would
like to do is subclass the "list" built-in type.  What I've got seems to
work, kinda.  I can subclass and get myself a list, etc.  My problem is
that I'm segfaulting when I raise an exception in __init__.  Here's the
Pyrex code:

[[[

cdef extern from "Python.h":
     ctypedef class types.ListType [object PyListObject]:
         pass

cdef class test4(ListType):
     def __init__(self):
         raise StandardError

]]]

And I get this from python:

[[[

 >>> import testMod
 >>> a = testMod.test4()
Segmentation fault

]]]

Is it not possible to raise an exception from the initializer of an
extension type?  Or am I going about the inheritance all wrong?  Can  I
subclass the list type?

Thanks,

michael
