--- Comment #1 from Eric Fiselier <eric at efcs.ca> ---
Fixed in r337205.

The fix is to simply remove the attribute when it's not supported (GCC on Apple
and MSVC). For GCC 7 and 8, the attribute was unneeded anyway, since they
support C++14 and that allows `ResourceInitHelper` to be initialized using
constant-initialization at compile time.

The init_priority was only needed for older GCC compilers which don't support
C++14.
