I've tried a few builds by reverting these changes but still the issue is reproducing. There are a few commits in 85c0ce2 for src/bootstrap/src/core/builder.rs & src/bootstrap/src/bin/rustc.rs files which have changes related to remap-debuginfo option and I suspect this commit might causing the issue. I tried build by reverting the commit & with the latest changes in 4b7e0a0 but still issue is reproducing. Further discussion is on-going with upstream. https://github.com/rust-lang/rust/issues/120825 98328 2 sundeep.kokkonda 2024-02-26 14:44:31 +0000 During the build absolute path names are found in many stages but all are replaced/remapped as per '--remap-path-prefix' command by end of the build except the '.rustc' section contents. I see that the .rustc section of 1.74 libs having the path names with '/rust/$hash' format. Below is the contents of libdarling_macro-*.so file. /rustc/a28077b28a02b92985b3a3faecf92813155f1ea1/vendor/darling_macro/src/lib.rs Where as in 1.75 this is having absolute path names /home/skokkond/rust/rustc-1.75.0-src/vendor/darling_macro/src/lib.rs Updated the analysis so far in rust community: https://github.com/rust-lang/rust/issues/120825#issuecomment-1964307219 98514 3 sundeep.kokkonda 2024-03-18 04:10:28 +0000 Issue fixed with below commits: https://git.openembedded.org/openembedded-core/commit/?h=master-next&id=457422ecb25480f9dae1adc7730062770a924487 https://git.openembedded.org/openembedded-core/commit/?h=master-next&id=457422ecb25480f9dae1adc7730062770a924487 98515 4 sundeep.kokkonda 2024-03-18 04:12:02 +0000 Issue fixed with above mentioned commits in Comment #3. 98536 5 randy.macleod 2024-03-19 20:34:52 +0000 Sundeep, I've re-opened the bug so you can provide links to a branch other than master-next.
