Single stepping inside shared lib functions on ARM

["Dheeraj V.S." <dheerajvs at huawei dot com>]

I'm remote debugging on an ARM target using gdb 6.5.
I'm unable to step into functions that are defined inside shared libraries
although the identical .so file is accessible both by the host and target.

These are the test programs used (both compiled using gcc version 3.4.4 with
-g option):

linux:/home/dheeraj # cat gdb_test.c
#include <stdio.h>

void function ()
{
  printf ("In function\n");
}

extern void function_in_lib();

int main ()
{
  printf ("In main\n");
  function();
  function_in_lib();
  printf ("Quitting\n");
  return 0;
}

linux:/home/dheeraj # cat gdb_test_lib.c
#include <stdio.h>
void function_in_lib ()
{
  printf ("In function_in_lib\n");
}

The following is the output of gdb 6.5:
Note the lines with the arrows (<----)

(gdb) n

(gdb) c

I tried the same using gdb 5.3. This time, I don't get the errors like
"Cannot access memory at address 0x0" and "Cannot find bounds of current
function", but I'm still unable to step into the shared lib function. In gdb
5.3, the "step" command is treated as a "next" command for the shared lib
function.

Similar problems were reported in some list archives, but I've not found a
solution that works.
Any help is appreciated.
