--- Comment #4 from Patrick Moran <patrick.a.moran at gmail dot com> --- This bug does indeed seem to be related to / duplicate of c++/52830. That is, the two bugs reports are referring to the same trigger, but the bug manifests differently in the two versions (in the 4.9.0 I tested, I got this error, in the 4.8.0 it tested they got ICE). When I built c++/52830's test case with 4.9.0, I got this error message. A bit unsure of the ettiquette here - as the original reporter is it appropriate for me to go ahead and mark this ticket dup?
