checkbufferoverrun: remove dead store
...
the variable was declared inside a loop and the dead store also took place inside the loop (guarded by a condition) without further access of the value after that store.
Found by clang analyzer.
Was:
lib/checkbufferoverrun.cpp:1223:17: warning: Value stored to 'tok' is never read
tok = tok->next();
