--- Comment #5 from Ben Woodard <woodard at redhat dot com> ---
I think from a morphological level, I’ve got basically 4 clumps

There are the ones which have no information like binutils and eccodes
sometimes they are arch specific which makes me wonder if there are two things
in there. The original bug which manifested this is the one for binutils 29299
however probably the best example is eccodes.

Then there are the ones like darktable 29414 which are confusion between
typdefs and structs, template instantiations, or classes. I think that these
are regressions from the past couple of patches.

Then there are the ones which are C++ related and show up as a rather large
number of filtered errors and also vtable changes 29407

Finally there are ones which seem to be some size confusion in the types. One
package that exhibits this is hercules. I want to see how the other fixes
finally play out before I file that one.

With the 2.5 test run nearing completion we currently have 42 packages which
have self-compare problems. Dodji is expecting rather significant changes to
the C comparison engine when he lands the binutils fix. I'll do another test
run at that point see how many of these were resolved.

Unsorted list of packages which have self-compare problems:
389-ds-base
arm-none-eabi-gcc-cs
binutils
crash
darktable
eccodes
enlightenment
freefem++
gsoap
hercules

kdepim-addons
kf5-libktorrent
kf5-mailcommon
kim-api
kscope
lammps
libcouchbase
libomp
libXt
lighttpd
llvm
mono
nest
octave
OpenMolcas
openmpi
pocl
proxysql
qgis
qt6-qtbase
redis
