I am using this version of github to test, and the results as follows

 

https://github.com/lua/lua/tree/af6d9f31165a13c34c0601f37ca5a67c365d1d01

 

msvc15.9/release/64bit LUAI_MAXCCALLS <= 1492

msvc15.9/release/32bit LUAI_MAXCCALLS <= 1698

Lua avoids stack overflows by counting the number of recursive calls

it makes. The constant LUAI_MAXCCALLS sets this limit, but it is hard

to find the "perfect" value for each system. Can you play with

this constant (either with -DLUAI_MAXCCALLS=<somevalue> or changing

its value in 'llimits.h' or anything equivalent) and tells us

which is the maximum value where the crash becomes a regular Lua

error?

 

Many thanks,
