New issue 8314 by [email protected]: new UMR in AutocompleteEditViewWin::SetSelectionRange http://code.google.com/p/chromium/issues/detail?id=8314 It's unclear which checkin started this happening. Looking at the code, it doesn't make sense to me why this struct would be uninitialized. Dean's recent checkin rearranged a lot of the code in this file, so he speculated that maybe something about the edit control is in a messed up state at this point.
