** Emacs built with tree-sitter crashes when some *-ts-mode is turned on.
The crash is in many cases an abort due to run-time detection of stack
smashing, and it happens when one of the *-ts-mode modes is turned on
in a buffer.
The reason is that the tree-sitter library changed its Application
Binary Interface (ABI) between version 0.22.2 and 0.22.4, but did not
increment the ABI version number. Therefore, Emacs compiled with
tree-sitter versions before the change will try to use the shared
library after the change, and crash due to incompatibilities in the
ABI.
Until and unless the tree-sitter developers release a library with an
updated ABI version, the solution is to rebuild Emacs with the actual
library with which it will be used. If you cannot rebuild Emacs,
downgrade your tree-sitter library to version 0.22.2 or older.
The relevant tree-sitter issue is here:
