Subject: Fix display of complex local data types in GDB-MI
X-Git-Tag: emacs-25.0.90~1224^2~181
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=17fff76fea2b15a52d03f74d2dedbaec58330a4f;p=emacs.git

Fix display of complex local data types in GDB-MI

* lisp/progmodes/gdb-mi.el (gdb-locals-handler-custom): If a
variable has no value, display "<complex data type>" as a
placeholder, instead of a confusing "nil".  (Bug#21438)
