            Bug ID: 15668
           Summary: Cannot find bounds of current function
           Product: gdb
           Version: 7.5
            Status: NEW
          Severity: normal
          Priority: P2
         Component: backtrace
          Assignee: unassigned at sourceware dot org
          Reporter: vijunag at gmail dot com

I recently upgraded my compiler to gcc-4.7.2/glibc-2.17. Im unable to debug the
executable after calls to few functions which have hand written assembly in
glibc.

Below are the gdb debugging excerpts when one line at a time are executed.
(gdb) r
Failed to read a valid object file image from memory.
Breakpoint 1, main (argc=5, argv=0xbffff784, env=0xbffff79c) at main.c:205
205    int main(int argc, char **argv, char **env) {
(gdb) n
220        FILE *rva = fopen("/proc/sys/kernel/randomize_va_space", "r+");
(gdb) n
221        if (rva) {
(gdb) 
222          int val=0;
(gdb) 
224          if (1==fscanf(rva, "%d", &val)) {
(gdb) 
225        if (val) {
(gdb) 
237          fclose(rva);
(gdb) 
242          } else if (val) {
(gdb) 
273      main_config.argv0short = strrchr(argv[0], '/');
(gdb) 
0x08048430 in ?? ()
(gdb) 
Cannot find bounds of current function
(gdb) 
Cannot find bounds of current function
(gdb) 

However if I step-into strrchr function I can proceed debugging further.
