Tree-sitter Fails with Core Dump on Processing Large Input Code File about py-tree-sitter

[amaanq]

Ah, I can reproduce with 0.20.1. Can you please use 0.20.4 instead? 0.20.1 is quite old

I cannot reproduce - I just built tree-sitter-c with cc parser.c -o parser.so -ltree-sitter -fPIC -shared

If you can provide some more info or some kind of debugging info like a backtrace that'd be helpful.

Hi, Thanks for taking this up. Here is the stack trace output. I have tried the above code with python 3.8 here. Maybe you could please use the pip version of tree-sitter (pip install tree_sitter==0.20.1) . Thank you.

Thanks, latest version works fine.
