            Bug ID: 17669
           Summary: edit command wrong source line
           Product: gdb
           Version: 7.8
            Status: NEW
          Severity: normal
          Priority: P2
         Component: cli
          Assignee: unassigned at sourceware dot org
          Reporter: kraftcheck at gmail dot com

The source line passed to the editor for the 'edit' command appears to
consistently be off by five.  The script below will produce this output:

  Breakpoint 1, main () at test.c:3
  3      int i = 5;
  edit +8 /tmp/test.c

Note that source line is 3.  Line number passed to editor is 8.


#!/bin/sh

GDB=${HOME}/opt/gdb-7.8.1/bin/gdb

cat >test.c <<end_of_source
int main()
{
  int i = 5;
  int j = 6;
  int k = 1;
  return i - j + k;
}
end_of_source

gcc test.c -g -o test

cat <<end_of_gdb | EDITOR=echo $GDB test
b 2
r
edit
q
end_of_gdb

--- Comment #1 from Jason Kraftcheck <kraftcheck at gmail dot com> ---
Script and output don't quite match up.  Corrected script (cosmetic change).

#!/bin/sh

GDB=${HOME}/opt/gdb-7.8.1/bin/gdb

cat >test.c <<end_of_source
int main()
{
  int i = 5;
  int j = 6;
  int k = 1;
  return i - j + k;
}
end_of_source

gcc test.c -g -o test

cat <<end_of_gdb | EDITOR="echo edit" $GDB test
b 2
r
edit
q
end_of_gdb

I wonder if this is related to the list window size.

Yeah, simple experiments suggest it is.

E.g., do "set listsize 1", and I get the cursor on the right line.
