--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
[except.terminate] allows std::terminate to be called without stack unwinding
in some cases, but I don't think that applies here. The standard specifically
says "An implementation is not permitted to finish stack unwinding prematurely
based on a determination that the unwind process will eventually cause a call
to std::terminate()." That seems to be what's happening here.
