Hi,

I configured to build emacs from source -- branch feature/tree-sitter and
commit 02f78c09b0a97ba044a43682a366a9d7732b885d -- invoking configure as
bellow:

../configure --with-json --with-imagemagick --with-x --with-tree-sitter
CFLAGS="-ggdb -O2" --enable-profiling

and build with make -j4. Then  I ran make -j4 check and all tests passed.

If all the forms below are evaluated with M-x eval-region -- after
launching Emacs with emacs -Q, the (*empty file*) /tmp/test.py is opened
but any key press (e.g. RET) kills emacs with SIGSEGV.

(setq python-use-tree-sitter t)

(and python-use-tree-sitter
     (treesit-available-p))

(setq treesit-extra-load-path
"~/emacs-tree-sitter/emacs-devel/admin/notes/tree-sitter/build-module/dist")

(find-file "/tmp/test.py")

Launching  Emacs with GDB and repeating the above steps reveals that the
SIGSEGV happens at:

treesit_load_language (language_symbol=<optimized out>,
signal_symbol=0x7fffffff6f90, signal_data=0x7fffffff6f98) at
../../src/lisp.h:1519
1519  return lisp_h_XCAR (c);

Any idea what I might be doing wrong? I downloaded libtree-sitter-python.so
from here <https://github.com/casouri/tree-sitter-module/releases/tag/v2.1>
and built from source.
