Subject: Port .gdbinit to unsigned-pointer platforms
X-Git-Tag: emacs-27.0.90~4984
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=a37166eb80458e87880893e7b8aa98a2a7ce394b;p=emacs.git

Port .gdbinit to unsigned-pointer platforms

* src/.gdbinit (Lisp_Object_Printer.to_string):
Don’t assume that GDB treats C pointers as signed integers.
Problem found with GDB Fedora 8.1-15.fc28.
