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) Sebastien
