[vox-tech] gdb: until doesn't work as advertised?

[Peter Jay Salzman]

argh.   this could get confusing...  let me try again:


p@satan% gdb until_demo
gdb: Symbol `emacs_ctlx_keymap' has different size in shared object,
consider re-linking
(gdb) break 9
Breakpoint 1 at 0x8048420: file until_demo.c, line 9.
(gdb) l

4       {
5               int i=0, j=0;
6               scanf("%d", &i);

8               while (i) {
9                       i--;
10                      j++;
(gdb) commands
Type commands for when breakpoint 1 is hit, one per line.
End with a line saying just "end".
>printf "i is %d\n", i
