dwarfdump output with overlapping ranges

I am using the dwarfdump command with these options -fFpPEo against a binary file. The output looks like this:

    fde:

The questions is why do a get the clear function several times? Why the address ranges overlapp? How can i tell which function is actually used?

Thanks,
