After [posting to OC forum](https://oc.cil.li/index.php?/topic/1795-preemptive-multitasking-and-sysyield-timeouts/), it turned out...
When optimising, the compiler is allowed to reorder the read calls in the following code: return (uint16_t)read_uint8_t(info) | ((uint16_t)read_uint8_t(info)
For performance reasons Lua does not initialise memory until it knows the values will actually be used. However Eris serializes some of them without knowing whether they have been initialised,...
If Lua targets a fixed point number system (like PICO-8 does) then the result of 0/0 may not follow the IEEE NaN semantics where x ~= x. In order to...
When investigating a bug report of OpenComputers I found that some lua code can behave incorrectly between loads (restoring the world after closing it) https://github.com/MightyPirates/OpenComputers/issues/2598 The summary of the problem...
