yeh...the comparison series is built with dtype=int, which is platform dependent; and the rhs side defaults (as it wasn't specified to int64), so either need to change to np.int64 in Series construction or set check_dtypes=False in the assert

(prior to 0.11, the Series would always upcast, now that dtypes is supported #2708, can get test failures like this)

[jreback]

this doesn't fail on 64-bit and isn't tested on travis (as it requires matplotlib I guess...and don't build with that), should we?

[ghost]

mpl is available in the FULL_DEPS build. Check the bottom of the log for installed versions:
https://travis-ci.org/pydata/pandas/jobs/4745031

are you sure the tests are not run?

[jreback]

oh...didn't think they were running because this test has not failed on travis....and given what other tests I had to change on 32-bit I think this WOULD fail....odd

[jreback]

@lodagro which arch is this failing on?

[lodagro]

Linux ubuntu 3.2.0-37-generic #58-Ubuntu SMP Thu Jan 24 15:28:57 UTC 2013 i686 i686 i386 GNU/Linux

Test is ok, if i set dtype to np.int64 iso int.
