Dear all,
I tried to use numpy (version 1.9.1, installed by `pip install numpy`)
on cygwin64. I encountered the following weird bug:
>>> import numpy
>>> with numpy.errstate(all='raise'):
... print 1/float64(0.0)
inf
I was expecting a FloatingPointError, but it didn't show up. Curiously,
with different numerical types (all intxx, or float128), I indeed get
the FloatingPointError.
Same thing with the most recent git version, or with 1.7.1 provided as a
precompiled package by cygwin. This behavior does not happen on cygwin32
(I always get the FloatingPointError there).
I wonder if there is something weird with my config, or if this is a
genuine reproducible bug. If so, where should I start looking if I want
to fix it? (I don't know anything about numpy's code)
