apart from the fact that dumpOSC uses some pointer casting magic.
this seriously screws up, when you just use the code in a naive way and
turn on compiler optimization.
(gcc>=3.0 and "-fstrict-alignment" cannot be used in conjunction with
pointer reinterpret casts)
i just recently discovered this problem in one of Pd's
OSC-implementations [1], which is basically a copy'n'paste of dumpOSC.

if you want to use dumpOSC code and use compiler optimization at the
same time, you should fix this e.g. by explicitely using unions.
