obviously it shouldn't crash, but what you're trying won't work, because
initializer_list::size is not constexpr, so il.size() is not a constant
expression

Indeed, according to the FDIS size() is *not* constexpr, but I had initially
just checked the GCC implementation, in which it *is* declared as constexpr!

(The original code is of course valid if you use -fwrapv, so hopefully the
problem optimization does not occur in that case.)

We should consider our users. GMP has been working with
GCC for a long time. Now it fails with GCC 4.7. It is
a very bad GCC 4.7 experience for user.

Ah, thanks also for the clarification. Anyway, at least now the error message
makes clear why *exactly* the functions isn't viable as constexpr.
