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}
