Problem solved, thanks to Shmuel Zeigerman and Soni L.
After wrapping in lua_checkstack, the code works perfectly even with
1000
tables.
Seems, like lua_checkstack grows the stack =)

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

By the way, why not to grow the stack automatically in pushing API
functions?
Because of overhead. Imagine checking the stack every operation vs
checking
the stack once for 1000 operations, or however many you need.
If the stack has room for new element, than the check is just one
comparison, which would be perfectly predicted.
