BLD: 32-bit / 2.7 tests broken

not sure what exactly broke this

@jreback : The failure started occurring about four days ago. My guess is that #17062 is the culprit given that it was merged around the same time, and the location of the failure is near the location of the files that were modified.

Being unable to reproduce, I made the following simple experiment: I added error-triggering lines to each function I had modified in #17062 . The test still works fine. So the bug doesn't seem to be related to my patch.

@toobaz : You can try reproducing via VM, but given your comment, that might be indicative of a flakey test, though not entirely sure.

Tests seem to be passing again: https://travis-ci.org/MacPython/pandas-wheels/builds/259204266

Not 100% sure what happened to fix it, but closing for the time being (but will monitor).

still recurring. I think this has to do with the factorization on 32-bit somehow.
