@LiamTheProgrammer I pushed a debug version of the bootloader that prints additional information when this error occurs. Could you replace your bootloader dependency by:

bootloader = {git = "https://github.com/rust-osdev/bootloader.git", branch = "debug"}

And then try to run your project again?

The error should still occur, but this time it should show the full llvm-size output as part of the panic message. This should help us debug this issue.

@phil-opp I managed to fix my issue. I forgot how, but here are the commands that I used:

@LiamTheProgrammer Thanks for the update! Since we both can no longer reproduce this issue, I'm going to close it. Let me know if it occurs again, maybe we can debug it then.

Hey, I'm now experiencing this bug. I'm on NetBSD 9.0 with cargo version cargo 1.49.0-nightly (d5556aeb8 2020-11-04). When I try to build the bootloader, I get the error thread 'main' panicked at 'unexpected llvm-size line output', build.rs:155:39. Do you have any ideas on what this could mean?

@monarrk Sorry for the late reply! If you still have this issue, try the debug instructions I mentioned above: https://github.com/rust-osdev/bootloader/issues/56#issuecomment-502457219
