Crushed by what? Weakly-interacting bosons can't crush you with pressure.
As far as gravity goes, as long as you're on a direct trajectory towards the center, you'll be free-falling so won't experience a gravitational "force" in your own reference frame.
The comment you originally replied to was talking about "a non-interacting boson star," i.e. a boson star made up one of the hypothetical types of boson that makes up dark matter.
In that case, the only significant interaction between those bosons and you would be gravity which, when in free-fall, affects the path you follow but won't in itself crush you. This assumes that (a) that there's not much normal matter in the star to crash into, and (b) that the mass is not large enough to generate deadly tidal forces. That's why the OP specified "a clean solar-mass boson star".
But it's worth noting that a "clean" non-interacting boson star can't really form in the normal way, since the bosons in question don't interact with each other in any way that would allow them to form dense clumps. You'd need some normal matter to provide a kind of anchor. In that case you'd see a more normal-looking object that just happens to be heavier than it should be given its visible composition, and you wouldn't be able to "drop through it."
