But if, for some reason, the pre-conditions are 212 212 not satisfied in a release build, the program will still behave sanely 213 213 and will not do an undefined memory access. 214 214 215 215 <p> 216 216 The testcase() macro is often used to verify that boundary 217 217 cases of an inequality comparison are checked. For example, at 218 218 [https://sqlite.org/src/artifact/18a53540aa3?ln=5766]. These 219 219 kind of checks help to prevent off-by-one errors.
