           Summary: [3.4 regression] tree-checking ICE in
                    eq_local_specializations
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: bangerth at dealii dot org
                CC: gcc-bugs at gcc dot gnu dot org

Attached is a piece of code that for me generates this: 
 
>>  c++ -c fe_system.ii -funroll-loops -O2 
fe_system.ii: In member function `void FESystem<dim>::initialize() [with int dim = 1]': 
fe_system.ii:50211:   instantiated from here 
fe_system.ii:49542: internal compiler error: tree check: expected tree_list, have goto_stmt in 
eq_local_specializations, at cp/pt.c:1017 
Please submit a full bug report, 
with preprocessed source if appropriate. 
See <URL:http://gcc.gnu.org/bugs.html> for instructions. 
 
It doesn't ICE with different compile flags, and it stops ICEing when I go to another  
machine :-( I don't have the time to track this down today, maybe someone else wants 
to look at this.
