This is a standalone reproducer with a total of 8k lines. It needs to be in
three different files, as fusing the 2nd and 3rd file eliminates the optimizer
problem of this issue, while fusing the 1st and the 2nd leeds to an ICE in
trans-array.c (reported separately) and is independent of this problem here.
The issue goes away with -O0, with -O1 and with -O2 -fno-tree-vectorize. 
I might want to find the offending commit in the week of June 12-19 in the
tree-optimizer, but I don't know whether I have time to do so. Hopefully, with
this 
smaller reproducer you can figure out what happens (and help solving it)
