Comment 1 Laura Pardo 2018-03-28 19:18:52 UTC

Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1561740]

Comment 4 Riccardo Schirone 2018-05-18 07:00:29 UTC

Statement:

This issue did not affect the versions of ImageMagick as shipped with Red Hat Enterprise Linux 5, 6 and 7 as they did not include support for OpenCL.
