It's just the old mode from Emacs 21.  The GDB grahical interface that uses
the "--annotate=3" option is much better.

I don't understand how the license info can be in the value of gdb-debug-log
as output is only logged after it's been printed

It's value (using `C-h v') should end something like this:

 (recv . "\n\x1a\x1apre-prompt\n(gdb) \n\x1a\x1aprompt\n")
 (recv . "\n\x1a\x1apost-prompt\n")
 (send-item "set width 0\n" ignore)
 (recv . "\n\x1a\x1apre-prompt\n(gdb) \n\x1a\x1aprompt\n")
 (recv . "\n\x1a\x1apost-prompt\n")
 (send-item "set height 0\n" ignore)
 (recv . "\n\x1a\x1apre-prompt\n(gdb) \n\x1a\x1aprompt\n")
 (recv . "\n\x1a\x1apost-prompt\n&\"\\n\\032\\032error-begin\\n\"\n&\"No registers.\\n\"\n~\"\\n\"\n~\"\\032\\032error\\n\"\n^error,msg=\"No registers.\"\n(gdb) \n")
 (send-item "server interpreter mi -stack-info-frame\n" gdb-get-version))

That may be the reason.  It should work on GNU/Linux but you don't say what
OS you are using
