You didn't say what does your dscript do to run GDB.  It's hard to
answer your questions without knowing that.  For starters, does it
invoke GDB with the -i=mi command-line switch?  If not, that's your
first problem.

Also, if you invoke GDB directly like the default prompt suggests,
does the problem go away?
