I am trying to use addr2line command in Unix but everytime it is giving the same output as ??:0. I am giving command as addr2line -e a.out 0x4005BDC . I got this address while running this a.out executable with valgrind tool to find the memory leakage. I also compiled the source code with -g option.

You can also use gdb instead of addr2line to examine memory address. Load executable file in gdb and print the name of a symbol which is stored at the address. 16 Examining the Symbol Table.

(gdb) info symbol 0x4005BDC
