Hi @ldionne,

Unfortunately this is breaking when trying to build Fuchsia with a clang version that includes this change. Here is a link to the build failure we're seeing:

There are places in the Fuchsia checkout that provide their own definitions of this function:

Can you make this backwards compatible and provide a means to transition to the `noexcept` version of this function?
