GDB 7.0, AFAIK.  But it's possible that some features need a newer
GDB.

If you invoke GDB from the shell with -i=mi, can you reproduce the
problem?

Also, do these commands appear in "info break" output right after you
define the breakpoint, or do you need the breakpoint to break a few
times before that happens?
