Sergey Semushin <Predelnik at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |Predelnik at gmail dot com --- Comment #5 from Sergey Semushin <Predelnik at gmail dot com> --- Had the same issue where the only dead code was leftover break in a switch case after return. Reasons are probably exactly the same but maybe in this form this issue will arise more often.
