             Bug #: 51852
           Summary: [regression] [c++11] tree check: expected tree_list,
                    have HßèMÕþÿøtxøtsø
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: zeratul...@hotmail.com


A C++11 program that compiled fine with the 2011-11-05 4.7 snapshot, fails to
compile with the latest (2012-01-07) snapshot, giving the following error:

tree check: expected tree_list, have HßèMÕþÿøtxøtsø
                                                   º in
eq_local_specializations, at cp/pt.c:1687


I have tried to reduce the program to a small test case, unsuccessfully - I've
gotten to the point where almost anything I try to remove makes the error go
away (and still the program is very long and includes proprietary code so I
can't post it). 

I can keep trying, and I will post the reduced testcase if I succeed, but I
thought I'd post the bug in case someone can figure it out just from the error
message.
