The ICE only happens with -fdevirtualize-at-ltrans:

trippels@gcc2-power8 library % g++ -flto -fdevirtualize-at-ltrans -shared @list
lto1: internal compiler error: in ipcp_verify_propagated_values, at ipa-cp.c:1057
0x10d1270f ipcp_verify_propagated_values()
0x10d1481b ipcp_propagate_stage
0x10d1481b ipcp_driver
0x10d1481b execute

I will try to come up with a testcase.
