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.

The C front-end does not add the duplicated label to the IR while the C++
front-end does.

if (DECL_INITIAL (decl) != NULL_TREE)
error ("duplicate label %qD", decl);
else
Maybe adding into the if condition:
POP_TIMEVAR_AND_RETURN (TV_NAME_LOOKUP, error_mark_node);
This might work but I have not tested it at all.
