Found by Coverity error: > CID 172193 (#1 of 1): Bad bit shift operation (BAD_SHIFT) > 1. large_shift: In expression 1 << sig % 64, left shifting > by more than 31 bits has undefined behavior. The shift amount, > sig % 64, is as much as 63. That is: 1. yes, UB 2. while adding a signal to mask, this has flushed all other signals from mask.
