I found a missing BLOCK_INPUT that may or may not be related to this:

=== modified file 'src/xfns.c'

  #ifdef USE_LUCID
    /* Prevent lwlib/xlwmenu.c from crashing because of a bug
       whereby it fails to get any font.  */
+   BLOCK_INPUT;
    xlwmenu_default_font = XLoadQueryFont (FRAME_X_DISPLAY (f), "fixed");
+   UNBLOCK_INPUT;
  #endif
  
    /* Frame contents get displaced if an embedded X window has a border.  */

Could you try if C-g works for you case on X11 builds, both
--with-sync-input and --without-sync-input?
