I've just applied the patches to all stable branches, and they all
applied fine, including the 4.6 ones. Are you perhaps missing the
XSA-235 fix there? In any event, as said a number of times in
the past, the patches we provide are against the staging branches
for the respective stable versions; we don't guarantee patches
apply to vanilla stable releases.
