[cfe-users] Reproducible builds

You could try something like this:

template <int N>
class X{}

static X<SOME_INT> x;

// or

char str[SOME_INT];

then compile it like this:

clang++ -D$RANDOM -c file.cpp -o file.o

RANDOM is a bash thing, but basically you just need to generate a random
number each time you compile and pass it in as a macro.
