OP_PHISOURCE's phi_users

Hi list,

struct instruction has a field, 'phi_users', used for OP_PHISOURCE to store their users. In other words this field is used to store the OP_PHIs instruction that use a given OP_PHISOURCE.

I'm wondering if someone would have an example where an OP_PHISOURCE is used by more than one OP_PHI.

I've searched, not too hard but still and I didn't found any. To be honest, I don't think it can happen and if it does I'm wondering what would be the associated meaning.
