There are known deficiencies in gcc's current location list information. There are two independent projects under way to address this: http://gcc.gnu.org/wiki/Var_Tracking_Assignments http://gcc.gnu.org/wiki/AndrewMacLeod (DEBUGLOCUS on that page) With luck one of those will eventually be committed to mainline and will address this issue.
