Re: segfault when lua_newtable called 100 times in a row

Rena, this example is extremely shortened. My goal is to decode json files full of tables.

for example, [[[[[[[[[[[[[]]]]]]]]]]]]]

Hello, community!

I am stuck with a problem: when I'm trying to add 100 tables in Lua c stack, I receive segfault on function end.

Code example:

lua_example.c: http://pastebin.com/GFvLwMY2

Makefile: http://pastebin.com/3EWJiVz7

test.lua: http://pastebin.com/1y22XvzK

Maybe I'm doing it wrong? What setting I should increase to be able to add 100 tables?

local variables limit is 200 by default, registers limit is 254, so I don't get it.

static int lua_example_test( lua_State *L ) {
    for ( int i=0; i<100; i++ ) {
        lua_newtable(L);
    }
    return 1;
}

What are you trying to achieve here? You're creating 100 tables but doing nothing with them, then only returning one?
