Subject [GitHub] incubator-quickstep issue #101: Optimize PackedRowStoreValueAccessor & Basic...
Date Mon, 03 Oct 2016 15:48:18 GMT
Github user saketj commented on the issue:

    It is strange that only one of the Travis build tasks for [clang++ compiler, build=release
and vector_copy_ellision_level=selection] is repeatedly failing due to a compiler error. 
(Reproduced below) . 
    The same code compiles perfectly for clang++ release (vector_copy_ellision_level=joinwithbinaryexpression)
and for all configurations of g++. 
    I don't think it is related to changes of current PR. I tried running it multiple times,
but still the same error. Does anyone else has also faced the same issue before, or might
know what is causing it?
