On trunk I see it fixed in r259672:

PR tree-optimization/85116
* tree-ssa-loop-ch.c (do_while_loop_p): A do-while loop should
have a loop exit from the single latch predecessor. Remove
case of header with just condition.
(ch_base::copy_headers): Exclude infinite loops from any
processing.
(pass_ch::execute): Record exits.
* gcc.dg/tree-ssa/copy-headers-2.c: New testcase.
* gcc.dg/tree-ssa/copy-headers-3.c: Likewise.
* gcc.dg/tree-ssa/copy-headers-4.c: Likewise.
* gcc.dg/tree-ssa/loadpre6.c: Adjust.
GCC 6 branch is OK, so it appeared in trunk in r250212
