This is a known bug with gcc. There is a bugfix (that i don't really
understand and consequently don't know if it is really accurate)
floating around for this one.
If in doubt, please file a PR in http://gcc.gnu.org/bugzilla/ about this bug
and perhaps add a pointer to the patch if this bug is not yet entered in
bugzilla.
TIA,
