Indeed I had missed that you can call it without a command, my mind must 
have skipped that line, thanks :)

However there is still a problem forcing me to use gdb_expect I think, 
namely mi_gdb_test waits for a command prompt like so :

-re "^($string_regex\[\r\n\]+)?($pattern\[\r\n\]+$mi_gdb_prompt\[ \]*)"

However dprintf does mean you will get a prompt printed...

You will get a prompt only when hitting the breakpoint I placed.

This means that if for some reason the breakpoint would not hit, the 
dprintf test would fail, when it's the breakpoint that should fail.

I could remove mi_expect_stop at the end and assume that breakpoint will 
not fail but I think it's not right ? also mi-dprintf.exp is using the 
same mi_run_cmd / gdb_expect / mi_expect_stop ...

What do you think ?
