    This is a regression in mainline. Steven was already
    close with his testcase (sent privately), here's a
    maximally reduced one:
    -----------------------------
    class A {};
    
    A const foo();
    
    void bar() {
      A a = foo();
      A b = true ? a : foo();
    }
    -------------------------
    g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c y.cc
    y.cc: In function `void bar()':
    y.cc:7: internal compiler error: in ocp_convert, at cp/cvt.c:636
    
    There's a note in the audit trail that it might be related
    to 10224. I don't think that's the case, and indeed Nathan's
    fix doesn't cure this report as well, so they are different.
