📃 SLua Alpha

One of my HUDs started producing errors only after I recompiled it from LSL/Mono to LSL/Luau due to an empty string "" being changed to an empty key, after every region crossing, before being passed to llSetLinkPrimitiveParamsFast . I distilled the issue down to this script: list myList = [""]; key someKey; // this must be below myList to reproduce this bug default { touch_start(integer total_number) { if (llListFindList(myList, [(key)""]) != -1) // we found an empty key in the list { llOwnerSay("FAIL: The empty string was changed to an empty key. Resetting..."); llResetScript(); } else llOwnerSay("PASS: The empty string is still an empty string."); } } Steps to reproduce Teleport to any Luau test region. Create an object and attach it to your avatar. Create a new script in that object and paste the above code into the script editor window. Change the compiler to LSL/Luau and then save the script. Click the object. It will output "PASS." Walk into an adjacent Luau test region. Click the object again. It will output "FAIL." Affected versions Luau 2025-03-10.13758278457

I think it crashes the region shortly after "succeeding". b = buffer.create(1024*1022) ll.Say(0, `created, size = {buffer.len(b)}`) will report a buffer of 1046528 bytes being created, and shortly after nothing goes through anymore and the region drops me. 1023*1024 bytes is too much and gets an out of memory error.
