Yes.

The most obvious one is probably that program A, which uses only dot
locking, and program B, which uses only flock(), will not understand or
respect one another's locks.

A more subtle one is that programs C and D, each of which does both
sorts of locking but in opposite orders, can deadlock with one another.
