Description Andi McClure 2016-09-22 22:24:23 UTC
This assert has been seen about four times over the last week, always on ARM64, apparently?? always while running the automated test MonoTests.System.Xml.Xsl.XslTransformTests.PreserveWhitespace

* Assertion at mini-arm64.c:937, condition `arm_is_bl_disp ((code), (target))' not met
