[Paul Eggert]

branch: master
commit a55a0483c939b7e0cc8b85d96a2fe8ac3fc6fb41
Author: Paul Eggert <eggert@cs.ucla.edu>
Commit: Paul Eggert <eggert@cs.ucla.edu>

    Pacify GCC 12 in x_get_current_wm_state
    
    * src/xterm.c (x_get_current_wm_state): When lint checking,
    initialize reply_data to a non-null dummy value instead of to a
    null one.  This pacifies GCC 12 -Wanalyzer-null-dereference.
