From cd16fadb9ccd7c99ee78e20c3239a5ddc9a938a1 Mon Sep 17 00:00:00 2001 From: George Burgess IV Date: Thu, 25 Jul 2019 06:53:59 +0000 Subject: [PATCH] [BasicAA] Temporarily disable two tests These tests are breaking three independent upstream buildbots (as well downstream ones). These breakages have appeared mysteriously, consistently, and during different revisions. Sadly, none of {ASAN,TSAN,MSAN,UBSAN} flag anything, so the cause here is nonobvious. Until we've figured this out, it seems best to disable these tests entirely, so that the affected bots don't remain silent about any other, unrelated failures.
