The bug report says that part is fixed, and only a ccp issue remains.
"The testcase in comment #2 works for me on the 4.2 branch now, but the one in
comment #7 fails with ... in tree-ssa-ccp.c"
Yes, this is a similar issue as PR30840 on the mainline, the CCP propagator goes
up the lattice in some cases. This is something Diego promised me to look at ;)
But we might be able to paper over this issue in 4.2 ...
