[Bug c++/17695] New: ICE when compiling with -g

["fsm at robots dot ox dot ac dot uk" <gcc-bugzilla at gcc dot gnu dot org>]

A simple piece of code (distilled below) gives ICE with -g but not without.
The behaviour has persisted over a week or so of CVS checkouts.


[Could an explanation of "host triplet", "target triplet" and "build triplet"
 be provided somewhere? I had to guess/google to find out what you wanted and
 I am still not sure it is right.]
