Confirmed. Works with -std=c++11. They might be dupes, but this one looks
valid.

Yes, issue is caused by prefix of INDIRECT_REF.
The following patch solves this issue for me:

Slightly reduced testcase:
void
f (int &c, int &lc)
{
c >> (lc -= 8);
}

This looks to me wrong. INDIRECT_REF has just one argument, and is directly
associated to underlying decl, so I don't see a reason to put it into the
refs-vector. To initialize it no additional constructor is required AFAICS.
But I might be wrong
