[Numpy-discussion] Crashes and test failures

Hi list,
I just got a new laptop, running Ubuntu 11.10 64bit on an Intel i7.
I am a bit intriged by the test results of numpy on this box.
First of all, master builds and imports OK, but the simplest test case
crashes with a segfault:
import numpy as np
a = np.ones(10, dtype=np.bool)
np.all(a)
Am I the only one to see this? If so, I am wiling to investigate, but
I'll need a bit of help, as I had a look with gcc, and the crash
seems burried deep in the guts of numpy.
Second, I backed out a bit, and checkout out the 1.6.1 tag. It builds
alright and doesn't segfault, but I am getting a few test failures
(pasted at the end of the mail). I haven't been following the mailing
list well-enough lately, so I am unsure: are these known failure. I was
surprised to find a tag that looked like a release with failures.
Sorry if I am asking stupid questions, finding master unusable at first
glance for me was a bit offseting.
