There are null bytes after `{"width":"4","alignment":"-1",'.  So it's
a small wonder that json.el chokes.  IOW, this is not a problem with
either json.el not gdb-mi.el, but a much more fundamental problem with
low-level Emacs functions that insert text into a buffer.

When did you last update from the emacs-25 branch?
