Building DMD on OSX with -O -inline -release -flto=full: https://github.com/dlang/installer/actions/runs/9023729802/job/24796283183

Judging from the error, only -flto=full seems to be important here.

Copy of logs.

Oh wait a second, that job uses macos-latest, which is now arm64 macOS 14. So default /usr/bin/cc might not really like x86_64 input. So I'd try reverting to a x86 macOS runner, either macos-13 or macos-12 as first thing.

Edit: https://github.com/dlang/installer/pull/576

Findings from that PR: looks Xcode v15-related, as the same assertion happens on macos-13 x86_64, with the same Xcode v15.0.1, but macos-12 with Xcode v14.2 works. https://github.com/dlang/installer/pull/576#issuecomment-2103645297

I almost forgot that I detest Xcode 15.0 - not only for asserting left and right, but also for being buggy as hell.
