[Numpy-discussion] 64bit check_manyways segfault.

[Arnd Baecker]

Hi,

with current svn I get a segfault for numpy.test(10, 10):

check_manyways (numpy.lib.tests.test_arraysetops.test_aso)Segmentation
fault

There are no "incompatible pointer type" during the build of numpy.
The backtrace is below.

I hope this has not been reported during the last two days
(I hardly manage to keep up with the traffic during the week ;-).

Best, Arnd
