--- Comment #4 from Mathias Stearn <redbeard0531 at gmail dot com> --- @Jakub, This code doesn't have either mutable or noexcept, so the "wrong place in the grammer" issue doesn't apply. That part of the fix seems correct and useful. While it seems correct to fix what the c++11-syle [[attribute]] appertains to to match the standard, it would be unfortunate to do the same to __attribute__(()) style attributes which are already outside of the standard. Until the standard provides some way to have an attribute that appertains to the lambda function, this part of the "fix" is breaking useful functionality that has existed since GCC-5 without offering any replacement.
