Package: src:gcc-9 Followup-For: Bug #954681 Control: reopen -1 Hello.
The initial symptom is cured, but the fix lets debian/patches/ada-lib-info-source-date-epoch.diff modify gcc/ada/libgnat/s-os_lib.ad[bs]. This invalidates the checksums embedded in the .ali files of libgnat-9, causing a failure in all Ada compilations involving packaged dependencies. Especially, all run time tests for packaged libraries fail. Ludovic suggests to revert the fix (commit c1d276b0e2cb60140389aa4c23ac3addb7a77af3 )in the gcc-9 branch. I suggest to cherry-pick the commit in the gcc-10 branch, so that it is part of the future gnat-10 transition. Matthias, do you agree with these two actions? Then, we will search for a less intrusive work-around for this bug in gcc-9.
