[-- Attachment #1: Type: text/plain, Size: 274 bytes --]
Hello, I recently updated my Emacs following the master branch and
encountered a bug in gdb introduced in commit f6356dc88d23 which breaks
some of its buffers. I've attempted to fix it with this patch. Let me
know if I made any mistakes since it is my first contribution.

Subject: [PATCH] Fix string padding in gdb-mi
In commit f6356dc88d23eb405aa6d8bd9dd5f669f1bc45ee local padding
function gdp-pad-string was replaced with string-pad from subr-x. The
problem is that calls to string-pad use negative integers which result
in errors that prevent text to be displayed on gdb information
buffers. Now padding is stored as positive integers and calls to
string-pad check if they should be right aligned.
* lisp/progmodes/gdb-mi.el (gdb-table): Fix string padding in gdb-mi.
