- Spivak 2y agoI'm sure it's not literally no one but I bet the percent of additions that have explicit checks for overflow is for all practical purposes indistinguishable from 0.
- nox101 2y agoLots of secure code checks for overflow fillBufferWithData(buffer, data, offset, size) You want to know that offset + size don't wrap past 32bits (or 64) and end up with nonsense and a security vulnerability.
