Actually, it would be __OPTIMIZE__, but that wasn't the culprit. The 
function compareRanges is declared as follows:

static U_INLINE int32_t U_CALLCONV
compareRanges(const void *context, const void *left, const void *right);

And in another function used as an argument to a third function, i.e. 
pointed at with a pointer, but as it's inline you can't point at it.

Now the only thing left is to find out why the heck it fails with 
-O{0,1} but not >= -02...
