help: gud-debug with emacs

[Tom Hu]

Hi all,

I just updated my emacs to 21.2 (old version is 19.x). When I did single
step
"n" to debug my code, the cursor sometimes does not move to the right
source line. Until I did "l" to list the source, it will move to the
right position.

I did not see this problem in my 19.x release. I used the same init file
.emacs.

Thanks help

Tom Hu
