Neat trick. :) >I suspect it does and this relates to Apple Gdb and the previous problem with ^M >characters. Here's what I tried. 1. emacs -Q -nw foo.c 2. M-x gdb RET foo RET 3. M-x gdb-enable-debug 4. "b add_" [hangs] 5. C-g twice (stops hanging) 6. C-h v gdb-debug-log RET I'll attach the contents of the *Help* buffer as gdb-debug-log.txt. The last cons in gdb-debug-log.txt is (send-item ... "complete b add_\n"). The second and third cons's above (send-item) seem to contain the completion output. >You could also download and compile FSF Gdb on Mac (I can't remember if you >already have) and try that. I haven't had a chance to build an fsf gdb yet, but I'm downloading gdb-7.0.1 now. I'll try gdb 7.0.1 and let you know how it goes. Steve
