  "message": "Exit when ID overflow occurs in a fuzzing build (#4652)\n\nCurrently if an ID overflow occurs, spirv-opt (and other users of\r\nIRContext) emits a warning and starts returning 0 when fresh ids are\r\nrequested. This tends to lead to crashes - such as null pointer\r\nexceptions. When these arise during fuzzing they lead to auto-reported\r\nbugs.\r\n\r\nThis change uses an ifdef guard to instead gracefully exit as soon as an\r\nID overflow occurs when the build is a fuzzing build.\r\n\r\nRelated issue: #4539.",
