ThreadSanitizer doesn't work on aarch64？

[huangtianhua]

I build/test apache/kudu on aarch64, when I enable tsan then all tests are failed(they are success without tsan enable), the error info like:

+++++++++++++++++++++++++++++++++++++++++++++++
ThreadSanitizer:DEADLYSIGNAL
==6175==ERROR: ThreadSanitizer: SEGV on unknown address 0x000000000000 (pc 0x000000000000 bp 0xfffffffff0f0 sp 0xfffffffff0f0 T6175)
==6175==Hint: pc points to the zero page.
==6175==The signal is caused by a READ memory access.
==6175==Hint: address points to the zero page.

ThreadSanitizer can not provide additional info.
SUMMARY: ThreadSanitizer: SEGV (<unknown module>)
==6175==ABORTING
+++++++++++++++++++++++++++++++++++++++++++++++++++++++

I also print the sig info as:

(gdb) p sig
$3 = (const __sanitizer::SignalContext &) @0xfffff633ad68: {siginfo = 0xfffff633ada0,
  context = 0xfffff633ae20, addr = 0, pc = 0, sp = 281474976706768, bp = 281474976706768,
  is_memory_access = true, write_flag = __sanitizer::SignalContext::READ}

Ps: we use LLVM: 9.0.0

According to llvm documents, tsan support linux aarch64 platform, and I try the example mentioned in llvm document. So would you please help me, what's the problem to make all tests failed?
Thanks very much.

this isn't an AArch64 backend issue, but without a reproducer there's not much we can do about this one.
