--- Comment #3 from Dean Michael Berris <dberris at google.com> ---
Re-opening to reflect the most recent state: we should not be using anything
from the C++ standard library. This is based on the conversation we've had in
llvm-dev@:

http://lists.llvm.org/pipermail/llvm-dev/2017-October/118126.html

In particular:

"""
The sanitizers don't use any of the C++ std library.
More than that, they don't include *any* system headers in most of the
sources (exception is some OS-dependent .cc files).

This rule is *somewhat* documented, e.g.
tsan/rtl/tsan_rtl.h:

//   - No system headers included in header files (*).
//   - Platform specific headres included only into platform-specific files
(*).
"""
