A '''Crash''', '''Freeze''', or '''Hardlock''' is when the [[Threads#Game Thread|game thread]] of SM64 stops executing instructions (as opposed to a [[Softlock|softlock]], where the game is still running as normal but is stuck in a loop without any way to get out). Crashes can occur in several different ways, such as a game thread exception or an [[RCP]] (graphics) crash. | A '''Crash''', '''Freeze''', or '''Hardlock''' is when the [[Threads#Game Thread|game thread]] of SM64 stops executing instructions (as opposed to a [[Softlock|softlock]], where the game is still running as normal but is stuck in a loop without any way to get out).

|When a noise's pan is determined, it uses the position of the object to calculate the pan. When the object's absolute z-position relative to the camera is large (>= 22000 units) and the x-position relative to the camera is very negative (< -66000), an index for the pan will be generated outside of the bounds of the array for the pan. When the value outside of the array is an invalid float, the audio thread will crash (sound glitch). Does not happen when sound mode is set to Mono. | |When a noise's pan is determined, it uses the position of the object to calculate the pan.

|Manipulating the pendulum to rotate beyond the range of an int will error when truncating the float. Verification of this crash took 39 days.<ref>[https://clips.twitch.tv/TiredKnottyOrcaThunBeast-3MHslDyIHpEavrfG "Pendulum Crash" by rcombs]</ref> | |||
