[Message part 1 (text/plain, inline)]
 Hello

 Emacs (emacs -Q with X11) segfaults in xfns.c (create_frame_xic), at 
its initialization, if XIM pointer is set, but not XIM_styles pointer.

 The patch extends the check on xim pointer to add the XIM_Styles 
pointer too.

 The code is at least several years old (git blame write "2014-03" in 
26.3 branch). The bug is present in master, 27.1-rc1 and 26.3 branch.

 The bug triggers today in my settings (emacs 26.3 from my debian/sid 
with gdm3 and windowmaker), but I do not know exactly why yet.

 Have a nice day
 Grégory Mounié
