I'm not aware of any code in the Cocoa port that would set things relating to line endings (or anything else non-graphical -- it just renders glyphs and faces given to it by xdisp.c), but perhaps it's some kind of weird interaction with the system-detected line ending format?I've done that now and can confirm that GDB related buffers have an extra ^M atthe end of each line with an X11 emacs too.
OK, useful to know. What happens if you hit <Ret> in a gdb buffer -- do you get a ctrl-M then, or only when gdb itself (or gud?) outputs something? If the former, it must be some setting for the buffer itself, and we could track that down. If the latter, do you know which function gud is using to write to the buffer?
Also, is gdb run through a shell, and if so, which one? I tried to replicate this myself, but cannot. I did the following: M-x gdb <path-to-prog> <Ret>The gdb buffer that results has no ctrl-m's, even if I run the program. Could you provide a more precise recipe to induce the bug? (Or, I'm wondering if it depends on the shell...)
thanks, Adrian
