Seems like LTO requires the whole required dev-qt/* dependencies to be rebuild from gcc:12 to gcc:13:
| Code: | Sun May 7 19:44:45 2023 >>> dev-qt/designer-5.15.9
Sun May 7 20:34:18 2023 >>> dev-qt/qtgui-5.15.9
Sun May 7 20:36:38 2023 >>> dev-qt/qtquickcontrols-5.15.9
Sun May 7 20:43:21 2023 >>> dev-qt/qtquickcontrols2-5.15.9
Sun May 7 20:52:08 2023 >>> dev-qt/qtcore-5.15.9
Sun May 7 20:53:44 2023 >>> dev-qt/qttest-5.15.9
Sun May 7 20:54:59 2023 >>> dev-qt/qtconcurrent-5.15.9
Sun May 7 21:02:51 2023 >>> dev-qt/qtwidgets-5.15.9
Sun May 7 21:24:05 2023 >>> dev-qt/qtdeclarative-5.15.9
Sun May 7 21:25:57 2023 >>> dev-qt/qtdbus-5.15.9
Sun May 7 21:31:26 2023 >>> dev-qt/qtwayland-5.15.9
Sun May 7 21:31:42 2023 >>> dev-qt/qtx11extras-5.15.9 |
here.

| Why do you think that these rebuilds are required? Nothing in your post shows any errors or warnings, so it is not possible for us to evaluate whether LTO is relevant here. |

| That is helpful. It shows this is a problem if you use static libraries that have LTO bytecode in them. That is a generic problem any time you switch compilers while using static libraries with LTO bytecode, and is not specific to Qt. The question then becomes, why is this library static when the others are shared? |

same for me, thanks for listing them all. fixed one, stopped at the next error
unfortunately lto-rebuild does not list or recompile them, aswell as emerge @preserved-rebuild or anything else I tried
no idea about the static/dynamic thing, though |

No here 
However any reason why not to: | Code: |
emerge -1 dev-qt/qtgui dev-qt/qtquickcontrols dev-qt/qtquickcontrols2, etc...
emerge -1 kde-plasma/kwin |
?

| That could work, but it might be more efficient to build a list of all static archives that contain obsolete bytecode, then use emerge to rebuild exactly the packages that own them. Can file tell you which version of LTO bytecode is in a static archive? |
