ProcessRecord problem with recursion

[Marc Khouzam]

Hi,

I'm having problems with ProcessRecord and recursion.
It looks like the reverse-next operation behaves like
reverse-step when dealing with a recursive method.

I have GDB HEAD from the 18th of March, with the patches included in
http://sourceware.org/ml/gdb-patches/2009-03/msg00375.html
http://sourceware.org/ml/gdb-patches/2009-03/msg00005.html
http://sourceware.org/ml/gdb-patches/2009-01/msg00444.html

Here is a program and session that shows the problem:

GNU gdb (GDB) 6.8.50.20090318-cvs
[...]
(gdb) l
1       int factorial(int x) {
2          if (x == 1) return 1;
3          int result = x * factorial(x-1);
4          return result;
5       }
6
7       int main() {
8           factorial(5);
9           return 0;
10      }
(gdb) start
Temporary breakpoint 1 at 0x804847b: file a.cc, line 8.
Starting program: /local/home/lmckhou/testing/a.out 

Temporary breakpoint 1, main () at a.cc:8
8           factorial(5);
(gdb) rec
(gdb) s
factorial (x=5) at a.cc:2
2          if (x == 1) return 1;
(gdb) n
3          int result = x * factorial(x-1);
(gdb) n
4          return result;
(gdb) rn
factorial (x=4) at a.cc:5
5       }

Notice how the reverse-next(rn) command jumped to the end
of the next factorial method on the stack (x=4 instead of x=5).

Thanks

Marc
