From b7c308a1ad32af4198dcc7eaa73f44fef27dc8fc Mon Sep 17 00:00:00 2001 From: Pablo Tello Date: Tue, 22 Jan 2019 12:59:26 +0000 Subject: COMPMID-1887: Fixed segfault in validation tests. Added the option to initialise the CLScheduler with an external cl::Context. This allows more control over the order of destruction of the static members which caused the suite to segfault.
