That's OK, but if you are debugging then it'll be obvious what
happend by it being a null ptr dereference rather than an assert
failure. Hence if anything I'd just kill the ASSERT(bp)....

It just describes what the code does - I don't think it make the
code any clearer and makes it more likely that if we ever change the
code the comment will then be wrong...

I'd say this is probably the only bits of the patch that add value.
Can you split this one out by itself?

Cheers,
