Here we go again!
I wrote another piece of code that breaks all the computers on server like in #1333

If you run this code on several computers (two are enough), then all other computers on the server will stop responding and executing commands.

e = string.rep("=", 805306366)
c= "return [" .. e.. "[t]" .. e.. "]"
print(#assert(load(c))())

After a while, the computer running code will display the following message:

Error running computer
Too long without yielding
ComputerCraft may be installed incorrectly

Here is the logs:

Sorry for not marking it with area-Core label.

Thanks for the report! This is a known issue, just unfortunately a tricky one to solve - see #1580 for more information.

Actually, there is a minor change we can make here which should avoid this. Have somewhat fixed this in cc-tweaked/Cobalt@97d2f36. Of course, the underlying issue is you shouldn't be able to allocate gigabyte-long strings, which is a little tricker to fix :/.
