           Summary: [3.3?/3.4 regression] Spurious error with casts in ?:
                    expression
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: critical
          Priority: P1
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: bangerth at dealii dot org

Mark, I think this is due to your fixes for 10931/10990/... yesterday:
this doesn't compile any more though I think it should
---------------------------
struct B {};

int main () {
  B a;
  (i ? static_cast<B&>(a) :
       *static_cast<B*>(&a));
}
----------------------------

tmp/gg> ~/tmp/build-gcc/gcc-install/bin/c++ -c x.cc
x.cc: In function `int main()':
x.cc:5: error: `i' undeclared (first use this function)
x.cc:5: error: (Each undeclared identifier is reported only once for each
   function it appears in.)

I don't have a recent enough 3.3 branch, but if your patch went to
the branch as well, it should be investigated for 3.3.1 as well. The error
above is from mainline.
