Most bugs are in your error handling code
While reading What tools made you better programmer I came across a link to Error Handling in a Correctness-Critical Rust Project which included these two tidbits:
almost all (92%) of the catastrophic system failures are the result of incorrect handling of non-fatal errors explicitly signaled in software.
in 58% of the catastrophic failures, the underlying faults could easily have been detected through simple testing of error handling code.
