Package: gdb Version: 7.12-6 Followup-For: Bug #772039 Dear Maintainer,
I have an example of a source tree which, its program having been built, causes the GDB demangler to crash. The program in question is a Doom WAD editing tool called SLADE, and the source code can be found on github at: https://github.com/sirjuddington/SLADE The result of trying to debug this program is as follows: --- begin crash transcript mormegil@cocytus:~/games/wadediting$ gdb ./slade GNU gdb (Debian 7.12-6) 7.12.0.20161007-git Copyright (C) 2016 Free Software Foundation, Inc.
