Wonderful! I appreciate the answer.

I had, by the way, dug into the compiler source code finally to figure out
exactly what __cxa_atexit actually *did*. I'm curious as to why this is not
the default option, and why it is listed in the documentation as a
requirement for ABI conformance when it is, in fact, related to C++
correctness.
