I tried the builds by disabling the rcgu's with codegen-units = 1. But still the compiled rustdoc with single rcgu also differed. - The increase of codegen-units = 256 or lto = off or opt-level = 0 also doesn't solve the problem. Further analysis is on-going and upstream doesn't have any clue about the root cause of the issue. 99483 3 richard.purdie 2024-08-01 14:46:14 +0000 https://git.yoctoproject.org/poky/commit/?id=e2e7017350d0b5324811fef3b841f98b00273887 Great to have this fixed, thanks Sundeep!
