It seems string concatenations will not be caught by the ‘Tool taking long time, do you want to quit?’ warning.
I found this by a coding error where I was concatenating to the wrong string in a functions loop. It wasn’t an infinite loop but ran long enough to cause this error. Basically renoise freezes as your machine goes up to max memory usage. You do eventually get a system out of memory warning.
Take a long string:
local string = “asdlfkjlisfjdlkdjslkjlewjrtpvwjrtvjerltkvjtjuvrkaebtljerbotjeratbjoraetjboeraibtoirjaebotjaerotijboraetjborjetb”
Concatinate in an infinite loop
while true do string = string..string end
Terminal Output when run in testpad.lua:
*** not enough memory
Error when run from tool::
