RE: Stack overflow in luaO_pushvfstring

[Yongheng Chen <changochen1@...>]

Hi Reberto,

 

This is tested on Ubuntu16.04. I built it with –fsanitize=address.

 

I didn’t see any instruction on how to add `debug.setcstacklimit`. It seems that it is already set in luaconf.h.

 

Thanks,

 

Yongheng

That may be a problem due to how you compiled Lua. Have you tried a smaller

C-stack limit? Add the following in the beginning of your script and see

how it goes:

 

    debug.setcstacklimit(1000)

 

(It may be necessary a limit even smaller than 1000...)
