After r206943 I get the following failures with -m32:

FAIL: g++.dg/opt/pr52727.C -std=gnu++98 (internal compiler error)
FAIL: g++.dg/opt/pr52727.C -std=gnu++98 (test for excess errors)
FAIL: g++.dg/opt/pr52727.C -std=gnu++11 (internal compiler error)
FAIL: g++.dg/opt/pr52727.C -std=gnu++11 (test for excess errors)

The ICE is

r206942 is OK.
