Description Rhys Ulerich 2011-12-07 17:14:44 UTC

Using http://bitbucket.org/eigen/eigen/get/3.1.0-alpha1.tar.bz2 on
Intel 11.1 I see a runtime failure in
       513 - evaluators (Failed)
The same test works fine for G++ 4.5.1.  Details on the failing
configuration follow.

- Rhys

Comment 1 Rhys Ulerich 2011-12-07 17:19:41 UTC

Notice this is at -O3.  Not sure what optimization level is supported for Intel.  Feel free to tell me to re-run it at -O2 if you like.

Comment 2 Jitse Niesen 2011-12-12 18:34:18 UTC

While this of course needs to be fixed eventually, evaluators will not make it into 3.1. Would it make sense to disable this test for 3.1, or even remove this file and AssignEvaluator.h and CoreEvaluators.h temporarily and resurrect them when we branch 3.2? It could be quite confusing if we include code in Eigen 3.1 that isn't used anywhere.

Comment 3 Benoit Jacob 2011-12-12 18:46:12 UTC

Sounds like a plan.

Comment 4 Gael Guennebaud 2011-12-12 19:00:33 UTC

I agree with that too

Comment 5 Gael Guennebaud 2012-06-22 09:40:45 UTC

I resurrected the changes:

Comment 6 Christoph Hertzberg 2015-03-08 06:47:41 UTC

This unit test has been passing successfully for a while now.
