--- Comment #16 from Matt Godbolt <matt at godbolt dot org> --- I see the target milestone is 7.3, but this bug is still marked NEW. Has there been any further thought on this? I realise this is a tough one, but we've had to either disable LTO, or roll back to c++14 on our projects. It would be amazing if we could get this fixed :)
