--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
As said in the other PR, this is more for Honza who thought checking we do =
not
end with invalid profiles for all vect testcases is a good thing ;)

Btw, the wrong count pops up in DOM3:

t.c.203t.dom3:;;   Invalid sum of incoming counts 138435014 (estimated loca=
lly,
freq 3.0936), should be 134239200 (estimated locally, freq 2.9999)

so it seems to be a jump threading issue.  It's gone with -fno-thread-jumps.

Very likely a latent issue, but of course the change triggering this does
have an effect on jump threading.

Confirmed.=
