In the latest valgrind 3.10.0 a bug was fixed in valgrind.h for ppc32 (not that important since f21 dropped ppc32 support) and new support for aarch64 and ppc64le valgrind client requests. Some packages include their own private copy of valgrind.h (and possible memcheck.h, drd.h, etc) and won't get the bug fix nor the new architecture support. At least the following packages are affected. $ repoquery --whatprovides '/usr/src/debug/*/valgrind.h' \ --repoid=rawhide-debuginfo | sort -V 0ad-debuginfo-0:0.0.16-10.fc22.x86_64 condor-debuginfo-0:8.1.4-7.a1a7df5.fc22.x86_64 fwbuilder-debuginfo-0:5.1.0.3599-5.fc20.x86_64 gcr-debuginfo-0:3.13.91-1.fc22.x86_64 glib2-debuginfo-0:2.41.4-3.fc22.x86_64 gperftools-debuginfo-0:2.2.1-2.fc22.x86_64 libgnome-keyring-debuginfo-0:3.12.0-4.fc22.x86_64 libsecret-debuginfo-0:0.18-4.fc22.x86_64 lwp-debuginfo-0:2.6-10.fc22.x86_64 mono-debuginfo-0:2.10.8-7.fc21.x86_64 pidgin-debuginfo-0:2.10.9-5.fc22.x86_64 planner-debuginfo-0:0.14.6-17.fc22.x86_64 re2-debuginfo-0:20131024-3.fc22.x86_64 v8-debuginfo-1:3.14.5.10-13.fc22.x86_64 valgrind-debuginfo-1:3.10.0-1.fc22.x86_64 These aren't all packages. Some don't generate debuginfo and some might be compiled with valgrind support disabled.
I filed a FPC ticket to ask for how to handle this case correctly: https://fedorahosted.org/fpc/ticket/455
The package bugs are all closed now, but that is because f22 expired. There are still packages that have an embedded copy of valgrind.h. We should do another pass over all packages and see which have embedded valgrind.h, but don't Provides: bundled(valgrind.h).
The following packages still seem to embed a valgrind.h file instead of relying on valgrind-devel: condor-debugsource-0:8.8.15-7.fc37.x86_64 enlightenment-debugsource-0:0.25.4-1.fc37.x86_64 glib2-debugsource-0:2.74.1-2.fc37.x86_64 infinipath-psm-debugsource-0:3.3-26_g604758e_open.6.fc37.6.x86_64 julia-debugsource-0:1.8.0-1.fc37.x86_64 kf5-baloo-debugsource-0:5.99.0-1.fc37.x86_64 libgnome-keyring-debugsource-0:3.12.0-24.fc37.x86_64 libinput-debugsource-0:1.21.0-3.fc37.x86_64 mono-debugsource-0:6.12.0-9.fc37.x86_64 nvml-debugsource-0:1.12.0-1.fc37.x86_64 petsc-debugsource-0:3.17.4-2.fc37.x86_64 pipewire-debugsource-0:0.3.59-2.fc37.x86_64 pmdk-convert-debugsource-0:1.7-8.fc36.x86_64 upx-debugsource-0:4.0.2-1.fc37.x86_64 valgrind-debugsource-1:3.19.0-4.fc37.x86_64 webkitgtk-debugsource-0:2.38.2-1.fc37.x86_64
