[BUG] stack exhaustion in function `compile`, mujs

[ccxvii]

The recent commit will limit recursion during compilation, so should solve this issue.

I don't have clang-12 can it be replicated with clang-11?

[kdsjZh]

You can try with clang-11, pls let me know if it cannot be reproduced, I'll try to give you a set of instructions to reproduce via docker images.

[kdsjZh]

My steps to reproduce via docker, if you failed in your environment, you could try the following.

docker pull ubuntu:22.04
# start a container 
apt update && apt install vim git gcc make g++ wget libreadline-dev unzip -y
vim /etc/apt/source.list
# add clang's source for ubuntu 22.04, which can be found in https://apt.llvm.org/
# add gpg key
wget  https://apt.llvm.org/llvm-snapshot.gpg.key  && apt-key add llvm-snapshot.gpg.key
apt install clang-12 -y
git clone https://github.com/ccxvii/mujs && pushd mujs
wget https://github.com/ccxvii/mujs/files/8694862/poc0.zip && unzip poc0.zip
CC=clang-12 make build=sanitize && ./build/sanitize/mujs poc0

from mujs.
