In a private fork in this branch: https://src.fedoraproject.org/fork/mschorm/rpms/mariadb/commits/internal-compiler-error I've put the prepared rebase to mariadb 10.5.22 and on top of it several debug commits aims mostly minimize the reproducer. The last debug commit enables the debug build, and it is the only mode, in which the compilation succeeded. (build failed in %install phase , which if file) You can do a test builds from that branch with: fedpkg --release=rawhide build --scratch --srpm --arches=i686 That is how I produced the scratch builds https://koji.fedoraproject.org/koji/taskinfo?taskID=106357029 https://koji.fedoraproject.org/koji/taskinfo?taskID=106357363 https://koji.fedoraproject.org/koji/taskinfo?taskID=106358180 (this one is the debug build) If you want quick workaround, I think
%ifarch i686
%global _lto_cflags %{nil}
%endif
early in the spec file should do the trick, as it (unfortunately for me) isn't reproducible without LTO.
Will try to reduce it now.
Thank you for the workaround! It seems to be working well so far.
%ifarch i686
%global _lto_cflags %{nil}
%endif
I'll use it for the production builds, and potentially revert it later, once the issue is resolved, either on my, your or the upstream side.
From initial investigation, it looks like some LRA bug on debug instructions where it leaves a pseudo-register in one of them for some reason. So, another workaround might be to build i686 sql/item.cc with -g0 rather than -g, or perhaps just -fno-var-tracking-assignments. Now reduced and filed upstream as https://gcc.gnu.org/PR111497 Thank you Jakub. I haven't expected such a quick help and fast resolution. Well done, much appreciated 👍 This bug appears to have been reported against 'rawhide' during the Fedora Linux 40 development cycle. Changing version to 40. Upstream ticket closed as RESOLVED. I haven't encountered this issue recently. Closing Thank you for the fix ! |
I'm preparing a rebase of package 'mariadb' from version 10.5.21 to version 10.5.22. Exclusively on architecture i686, it gives me 'Internal compiler error(s)'. This is reproducible on all non-EOL Fedora versions. --- Sample: CMakeFiles/sql.dir/sql_get_diagnostics.cc.o -c /builddir/build/BUILD/mariadb-10.5.22-downstream_modified/sql/sql_get_diagnostics.cc /builddir/build/BUILD/mariadb-10.5.22-downstream_modified/storage/perfschema/ha_perfschema.cc: In member function 'delete_table': /builddir/build/BUILD/mariadb-10.5.22-downstream_modified/storage/perfschema/ha_perfschema.cc:473:8: warning: writing 1 byte into a region of size 0 [-Wstringop-overflow=] 473 | *ptr = '\0'; | ^ /builddir/build/BUILD/mariadb-10.5.22-downstream_modified/storage/perfschema/ha_perfschema.cc:455:8: note: at offset -1 into destination object 'table_path' of size 513 455 | char table_path[FN_REFLEN+1]; | ^ *** WARNING *** there are active plugins, do not report this as a bug unless you can reproduce it without enabling any plugins.

Actual Results: Internal compiler error Expected Results: Compiles If it would be on me, I'd rather stop building i686 variants of package 'mariadb', as I see no value in that. See https://discussion.fedoraproject.org/t/is-it-safe-to-stop-building-i686-builds-of-mariadb/90198 where I described it.
