This sounds highly related to Matthias' issue:

What version of systemtap headers and gcc are you using, that produce
this error?

If a cast really helps matters, I'd almost rather hide it within the
#define PROBE() than make callers have to worry about it, but I'm
reluctant to add a cast without knowing exactly why you are hitting
compilation failure.
