Subject: bug#17975: 24.3.92; assertion failure deleting frames with varying names for the same display (and, using multiple X11 connections in that case too)
Date: Sun, 13 Jul 2014 14:56:26 +0400 [thread overview]
Message-ID: <53C265DA.9070103@yandex.ru> (raw)
In-Reply-To: <53C26427.2050103@yandex.ru>
Just for the record: running Motif build with the same args, i.e.
./src/emacs -Q --eval '(let ((f (selected-frame))) (make-frame-on-display ":0") (delete-frame f))'
produces a hard crash caused by an attempt to dereference NULL
'Display *' pointer somewhere in Motif's libXm.so library:
Program received signal SIGSEGV, Segmentation fault.
