Since the buffer is displayed by display-buffer, any factor that affects 
display-buffer would affect this. I have a lower split-width-threshold, that 
makes it easier to split a new window. You can try to delete the I/O window in 
the default 6-window gdb layout. So source buffer has room to split to right. I 
just tried and this works on emacs -q.
