            Bug ID: 31352
           Summary: The sanitizers “address”, “memory” and “thread” are
                    mutually exclusive, but why?
           Product: clang
           Version: 3.9
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P

Hi clang developers,

When using sanitizer, it is clear that sanitizers “address”, “memory” and
“thread” are mutually exclusive, because:

clang-3.9: error: invalid argument '-fsanitize=address' not allowed with 
  '-fsanitize=thread'
clang-3.9: error: invalid argument '-fsanitize=thread' not allowed with
  '-fsanitize=memory'
clang-3.9: error: invalid argument '-fsanitize=leak' not allowed with
  '-fsanitize=thread'

Please give me some advice internal of clang, thanks a lot!

Regards,
Leslie Zhai
