With M-x gdb, gdb does not execute the first command (before prompt) and
gets stuck (freezes) with the second (during prompt).
With M-x gdba, it is exactly the same.

Here are some tests I have performed.

With M-x gdb:
Not doing anything before gdb prompt appears is OK.

Not doing anything but `M-x describe-variable RET gdb-ready' before gdb 
prompt appears tells "No match" and then commands make gdb freeze. Plus, 
hre are some messages I had:
   when: Symbol's value as variable is void: gdb-ready
   error in process filter: cond: Phase error in gdb-pre-prompt (got 
pre-emacs)
   error in process filter: Phase error in gdb-pre-prompt (got pre-emacs)

Note that all goes along with the --annotate=3 option.

With M-x gdba:
Not doing anything before gdb prompt appears is OK.

Not doing anything but `M-x describe-variable RET gdb-ready' before gdb 
prompt appears tells "No match" and then commands make gdb freeze.

The gdb-ready variable is defined everytime.
However, it is still set to 'nil' after the first prompt appeared.

With M-x gdb:
Not doing anything before gdb prompt appears, I receive this message:
when: Symbol's value as variable is void: gdb-ready

With M-x gdba:
Not doing anything before gdb prompt appears, it does not do anything 
until gdb is in the 'ready' state. Then it quits normally.



Thanks for your concern
