test()
In lua compiled in msvc2017, this code will cause a crash.
When you say crash, do you mean other than a normal Lua error and traceback? An error and traceback is to be expected with this code since infinite recursion like this will eventually overflow the call stack. This is what I get on Linux, compiled with gcc:

If that's what you're getting, then the behavior is correct. On the other hand, if you're getting a segmentation fault or some other strange non-Lua error, then I'm sure the Lua team would appreciate more details as to exactly what is occurring.
