I'm building in Debug mode with _SECURE_SCL = 0 and
_HAS_ITERATOR_DEBUGGING = 0. I'm in Debug mode so that the _Crt*
debug functions aren't compiled away since I was using those to track
memory usage.

Do you know of a better way to track memory usage in Windows? Task
Manager is obviously not up to the task, VTune reports it on a
system-wide basis, not per process, and _Crt* functions require
modifying your code.
