Eliminate 'if defiend(CHECK) to avoid having to different binaries for the same template function.

 There is a new crash report but not caught by the CHECKS.
(http://crash/reportdetail?reportid=accf4c24431527ce#crashing_thread)
This could be because this ifdef generates two different objects of this template function and linker may be picking bad one.
