27.0.50; running under gdb |
|
Date: |
Thu, 16 Nov 2017 22:17:55 -0500 |
I cd to src and type
gdb emacs
r
and I get the error message
there is no member named name
I am using GDB version 7.7.1 which is in Trisquel 7.
In principle I could install the latest GDB, but it would be a lot of work
and I doubt it would make a difference. I think the bug is in src/.gdbinit.
In GNU Emacs 27.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 2.24.23)
