            Bug ID: 33590
           Summary: EfficiencySanitizer-x86_64 workingset test failures
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: compiler-rt
          Assignee: bruening at google.com
          Reporter: bruening at google.com
                CC: llvm-bugs at lists.llvm.org

3 of the esan workingset tests are failing non-deterministically on some
non-public testing bots:

        esan/TestCases/workingset-midreport.cpp
        esan/TestCases/workingset-samples.cpp
        esan/TestCases/workingset-simple.cpp

They are failing with a SIGSEGV whose details and cause are not yet tracked
down.  This issue will be updated with details once they are known.  We expect
failures to start happening on the public bots as well as they seem to be
related to either recent hardware or Linux kernels.  For now we may disable
those 3 tests until the underlying cause is resolved.
