[Bug c++/17868] New: [3.3/3.4/4.0 regression] RDIV_EXPR not supported by dump_expr

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Compiling the following testcase with -pedantic, I get a hosed error message
with gcc 3.4.2:

=============================
struct A
{
    A(double);
};

const A& foo();

void bar(double x)
{
    foo()=A(x/2);
}
=============================

bug.cc: In function `void bar(double)':
bug.cc:10: error: no match for 'operator=' in 'foo() = A(#`rdiv_expr' not
supported by dump_expr#<expression error>)'
bug.cc:2: note: candidates are: A& A::operator=(const A&) <near match>

I have a fix for this. Will post patch soon.

Just for the record: the error message on mainline has another problem,
see PR 17867.
