Package: gcc-4.8
Version: 4.8.2-11
Severity: normal

Attached is a small C program.
It just takes the address of a label, and subtracts the address of the
function, to get the "size".

The problem is not directly related with that, though - the printf() output is
wrong.


When compiled with "-g -Wall" the output is as expected:

    $1 = 0x40
    Continuing.
    64

But with "-g -Wall -Os" I get

    $1 = 0x22
    Continuing.
    -317

so the information returned from the function is ok (gets smaller with -Os),
but the value used for printf() is wrong.
