Try running gdb outside of emacs, and use the --nx gdb command line option.

gdb --nx myprogram

and in emacs:

gdb --nx --annotate=3 myprogram

gud (emacs gdb) is not super robust.  It can get confused about the state of gdb when gdb has weird output.

Your "Current directory ...." should really be the first line.  Certainly, there shouldn't be anything after (gdb).  So, gud may well be confused.
