Bug #: 51728
Summary: [4.7 Regression]: libstdc++
25_algorithms/count_if/1.cc,
25_algorithms/partition_point/1.cc,
25_algorithms/search/1.cc SEGV ICE
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code, wrong-code
Severity: normal
Priority: P3
Component: regression
AssignedTo: unassigned@gcc.gnu.org

25_algorithms/partition_point/1.cc: cc1plus -fpreprocessed 1.ii -quiet -g -O2
-std=gnu++11 -o 1.s
These tests previously passed, now they fail.
Revision 182760 exposed or caused these regressions. Since then they fail as
follows:
Running

The messages in libstdc++.log are similar:
