--- Comment #1 from Erik Pilkington <erik.pilkington at gmail.com> ---
Compiling with exceptions enabled and the availability of
std::uncaught_exceptions in the libcxx dylib are actually unrelated. If you
want to use std::uncaught_exceptions on a program you're deploying before osx
10.12 then you should either guard the call in a `if (@available(macos 10.12,
*))` to check your OS version at run time, or use some macros from
<Availability.h> to check your deployment target at compile time.

Does that answer your question? I'm going to close this as invalid, feel free
to reopen if necessary.
