You should be able to write a GDB command file to do it. I think this
should work:

myprogram > tee savefile
display/i $pc
start

# Loop while the program hasn't finished
while($_exitcode == (void *)0)
{
   si
}

Although I haven't tested that, but if it is not that it is something
close. You can read up on command files in the manual, but basically,
write a file with the above in, then run GDB with the -x option.

eg: gdb myprogram -x myscript

Hopefully that will work. Appologies if I'm wrong, it's been a long
day of memory leak fixing  :(
