The reghunt is not yet complete, but the bad patch is between r179536 (good)
and r179566 (bad). In that range, I saw PR bootstrap/50621, and indeed
adding -fno-shrink-wrap removes the ICE, so I'm pretty sure r179553 is the
culprit here as well.
I'm attaching my testcase (preprocessed java/expr.c). With
$ cc1plus -fpreprocessed expr.ii -quiet -mno-synci -mabi=n32 -g -O2
it ICEs.
