Kangjie Lu <kjlu at gatech dot edu> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |UNCONFIRMED Resolution|INVALID |--- --- Comment #2 from Kangjie Lu <kjlu at gatech dot edu> --- Then I guess this is an unspecified area in C11. Anyway, the failure to initialize the padding bytes will cause information leaks; many leaks have been confirmed. I would suggest gcc to initialize padding bytes even it is not specified in C11. Thanks, Kangjie
