[Numpy-discussion] Segfault when indexing on second or higher dimension with list or tuple

[Albert Strasheim]

Hello all

I've attached a test case that reproduces the bug to the ticket:

http://projects.scipy.org/scipy/numpy/attachment/ticket/59/test_list_tuple_indexing.diff

I've also created a test case for the recent vectorize bug:

Regards,

Albert
