[cfe-dev] ARCMT test failures

[Jay Foad]

I'm seeing these failures from "make check-all" on Linux/x86_this morning:

Failing Tests (17):
    Clang :: ARCMT/alloc-with-zone.m
    Clang :: ARCMT/atautorelease-2.m
    Clang :: ARCMT/atautorelease-3.m
    Clang :: ARCMT/atautorelease.m

  Expected Passes    : 8669
  Expected Failures  : 69
  Unsupported Tests  : 551
  Unexpected Failures: 17

The failures all seem to be segfaults or assertion failures in arcmt-test, e.g:
