This is a regression that started in - gcc-6 when the ABI support code was updated to support overaligned - types. The fix is very similar in concept to the Arm fix. 128-bit - bit-fields are fortunately extremely rare, so I'd be very surprised if - anyone has been bitten by this. \ No newline at end of file |
