-------------------------------------

             Summary: Remove workaround for posix_memalign in SystemAllocator after LLVM 5.0 upgrade
                 Key: IMPALA-6259
                 URL: https://issues.apache.org/jira/browse/IMPALA-6259
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 2.11.0
            Reporter: Tim Armstrong
            Assignee: Bikramjeet Vig


Once we upgrade to LLVM 5.0 we should be able to remove a workaround for https://bugs.llvm.org/show_bug.cgi?id=32968:
{code}
#ifdef ADDRESS_SANITIZER
  // Workaround ASAN bug where posix_memalign returns 0 even when allocation fails.
  // It should instead return ENOMEM. See https://bugs.llvm.org/show_bug.cgi?id=32968.
  if (rc == 0 && *buffer_mem == nullptr && len != 0) rc = ENOMEM;
#endif

{code}
