[Message part 3 (text/plain, inline)]

gud-common-init function in emacs 27 seems to have a bug in how it calls
display-buffer. The second argument passed is ACTION. According to
docstring of display-buffer, the list of functions need to be a list
within a list. The attached patch adds the missing extra pair of
parenthesis.
