Per se, the issue is now moot because both in mainline and in 4_7-branch we
don't use std::log(2.0) anymore. Still, something may well be flaky, at least
for this specific version of darwin ("Snow Leopard", right?) vs the
optimization of the mathematical functions for compile-time constants... If
current 4_7-branch builds fine - I don't see why it should not - then it should
be pretty easy to create a small reproducer, just a tiny function calling
std::log(2.0).
