The C++ frontend stumbles over the following invalid code snippet since
GCC 3.4.5:

=======================
int foo()
{
  return i ""= i;
}
=======================

bug.cc: In function 'int foo()':
bug.cc:3: error: 'i' was not declared in this scope
bug.cc:3: error: expected ';' before string constant
bug.cc:3: error: assignment of read-only location
bug.cc:3: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in build_modify_expr, at cp/typeck.c:5720
Please submit a full bug report, [etc.]
