commit 3a5c4bdc0c079f72bad98e01f70343ba9e9b0043

Commit: Eli Zaretskii <eliz@gnu.org>

    Fix crash on MS-Windows due to memory-allocation problem in treesit.c
    
    * src/treesit.c (treesit_load_language): Use 'xstrdup'/'xfree'
    instead of 'strdup'/'free', to prevent crashes on MS-Windows,
    where we must use our own implementation of 'malloc'/'free',
    whereas 'strdup' uses the default implementation in the MS-Windows
    C runtime library.
