[reichelt at gcc dot gnu dot org]

The following invalid code snippet causes an ICE since GCC 4.0.0:

=======================
void foo()
{
    L: L: ;
}
=======================

bug.cc: In function 'void foo()':
bug.cc:3: error: duplicate label 'L'
bug.cc:3: internal compiler error: in record_in_finally_tree, at tree-eh.c:211
Please submit a full bug report, [etc.]

Only the C++ frontend is affected.
