Maybe I can help you here -
run
objdump -D -j .init_array <your-application>
and you will recieve a list of adresses, like
Disassembly of section .init_array:
c1008db4 <.init_array>:
c1008db4: c1000000 .word 0xc1000000
c1008db8: c1000a68 .word 0xc1000a68
c1008dbc: c1000b64 .word 0xc1000b64
c1008dc0: c1000c04 .word 0xc1000c04
c1008dc4: c1000c68 .word 0xc1000c68
now, if you have compiled this thing yourself, you can now run
addr2line 0xc1000a68 -e <your-application>
to get filename and line number of the functions in question.
Does that help?
