// Addr2line reads hexadecimal addresses, one per line and with optional 0x prefix,
// from standard input. For each input address, addr2line prints two output lines,
// first the name of the function containing the address and second the file:line
// of the source code corresponding to that address.

<p>
it can happen that <code>g</code> prints <code>2</code> and then <code>0</code>.

This fact invalidates a few common idioms.
