Try "nm -an" to sort by address, not size, and not skip any symbols.
Then you can determine for yourself what the "end of the function" is
and subtract the addresses.  If that doesn't work, try "objdump -d"
and it will show you the address of every single opcode - you should
be able to figure it out from that, even though the output file is
pretty big.

Note that gcc sometimes rearranges functions that are inlined.
