gud-gdb-marker-filter should pick up the prompt annotation first and then
change the value of gud-marker-filter to gud-gdba-marker-filter for further
output.

Can you give a reproducible test case that gives the error above or
this value for gud-last-frame?

This is almost certainly the wrong patch.
If you can't give a test case, please set gdb-enable-debug to t, do:
M-x gdb <RET>
Run gdb (like this): gdb --annotate=3 `your prog' <RET>
and send the value of gdb-debug-ring to emacs-devel.
