Thank you for helping out with this odd edge case! I don't suppose there's a way we can shove this hack into CMake (basically, like a kind of linker script hack)? If so, can we apply it broadly enough so that any use of `time_put` in other TUs will also benefit?

(If there are better alternatives than this approach, I'd love to hear about them, this is a pretty gnarly way to go about working around the issue.)
