Re: linux split-dwarf fails with -Clinker-plugin-lto

[cavivie]

I have reviewed the relevant bugs of rust, and I have a similar problem before that. Although it has been fixed, it still doesn't work for me. I don't know what happened. Only when I comment out split-debuginfo or set lto to false can I compile it successfully.

I tried many configs, there are three samples:

[profile.release]
opt-level = "z"
lto = true
debug = false
split-debuginfo = "unpacked"

[profile.release]
opt-level = "z"
lto = true
debug = true
split-debuginfo = "unpacked"

[profile.release]
opt-level = 2
lto = true
debug = true
split-debuginfo = "unpacked"

I believe this has already been fixed in the latest version (1.67), can you try a newer release?

Minimized example has no repro with latest stable. Probably is, in fact, already fixed, unless there's a more complex version that is not.

Thank you all very much! It works for me well now, I just forgot to close this issue🤭
