By title, I'm guessing you mean the screen session title.

Could you try changing the script to just have:

echo ppid=$PPID pwd=$PWD cmd="$@"
sleep 10


Screen's remote session creation unfortunately resets PWD (at least on my
machine), so the gdb command is expected to "fail" at opening the executable
(unless the original program was invoked with full path), but succeed at
attaching to the process ID.
