So other handlers can’t parse the message sent from gdb anymore. Thanks, pushed to the emacs-27 branch. Please in the future try to observe the following nits: > * lisp/progmodes/gdb-mi.el (gdb-handle-reply): > Handle error in ’handler-function’ so the cleanup code after it Please use quoting 'like this' in log messages (and also in NEWS). > + (condition-case err > + ;; protect against errors in handler-function Comments should be complete sentences, and as such, begin with a capital letter and end in a period.

If a handler produces = an error, cleanup code doesn=E2=80=99t get to run and leaves gbd-mi.el = in a corrupted state (in terms of communication buffer). So other = handlers can=E2=80=99t parse the message sent from gdb anymore.

Thanks, pushed to the emacs-27 = branch.

Please in the future try to observe = the following nits:

* lisp/progmodes/gdb-mi.el (gdb-handle-reply):

Please = use quoting 'like this' in log messages (and also in NEWS).

+ =      (condition-case err

Comments should be complete sentences, and as such, begin = with a

(I fixed all of these nits this time.)
