The purpose of the attached code is to print out the internal representation of
some floating points. However, when compiling with optimizations turned on the
behaviour of the compiled program is not the expected one (i.e. the proper hex
representation is not printed out, but something else, here 0). I encounter
this behaviour on amd64 debian as on windows using cygwin gcc.
I'm going to attach the debian output of compilation and invocation.
