--- Comment #1 from Don Breazeal <donbreazeal at gmail dot com> ---
Some other manifestations of this issue:
 * set a breakpoint on a blank line, then the breakpoint is set on the first
line of the next function (that has line info)

 * build a program containing an unused function with '-ffunction-sections
-fdata-sections -Wl,--gc-sections', and set a breakpoint in the unused
function.  the breakpoint will be set on the first line of the next function
(that has line info).

You can see this with the program in the attached file unused.tgz:

Reading symbols from ./unused...done.
(gdb) list
6         printf ("unused\n");
7         return;
8       }
9       
10      void
11      print_hello (void)
12      {
13        printf ("hello\n");
14        return;
15      }
(gdb) b 6
Breakpoint 1 at 0x4004ce: file unused.c, line 6.
(gdb) r
Starting program: /scratch/dbreazea/sandbox/test/unused/unused 

Breakpoint 1, print_hello () at unused.c:13
13        printf ("hello\n");

The same thing happens if you set the breakpoint on line 9, a blank line.
