#1869: np.place produce bad data with structured array columns as input
------------------------+---------------------------------------------------
Reporter: ged | Owner: somebody
Type: defect | Status: new
Priority: high | Milestone: Unscheduled
Component: numpy.core | Version: 1.6.0
Keywords: |
------------------------+---------------------------------------------------
It silently produce bad results, using data from all the array columns,
instead of just the one column I pass as argument.
with "a" being a structured array with several columns (let's say x and
y),
{{{
np.place(arr, mask, a['x'])
}}}
is roughly equal to:
{{{
np.place(arr, mask, a)
}}}
The problem is present in at least versions 1.4.1 to 1.6.0. See attached
test case for details.
