32 bit windows should not provide 16 byte alignment, at least it doesn't
for me. That is typically a property of 64 bit OS.
But that does not explain why normal double is not aligned for you, that
only needs 4 bytes on i386 which even 32 bit OS should provide.
I though I tested scipy on 32 bit li

When I do the following on 1.8.1 with win 32 bits:
x = np.zeros(12, "D")
print x.aligned.flags == (x.__array_interface__["data"][0] % 1
< 1.9 lies about alignment it doesn't actually check for new arrays.
is the array aligned?

Additional point: it seems to always return aligned data on 1.8.1 (same
platform/compiler/everything).

It is on windows 32 bits, but I would need to make this work for complex
(pair of double) as well.
Is this a bug (I assumed array creation methods would always create
aligned arrays for their type) ? Seems like quite a bit of code out there
would assume this (scipy itself does for example).

Hi,
I have not followed closely the changes that happen in 1.9.1, but was
surprised by the following:
x = np.zeros(12, "d")
assert x.flags.aligned # fails
This is running numpy 1.9.1 built on windows with VS 2008. Is it expected
that zeros may return a non-aligned array ?
