Sure.

These members were taken straight out of CurrentLineSection with the
intention of removing that class entirely, along with a couple others. I
believe that the original use for startOffset and endOffset are the
offsets to the beginning and end of the function in memory from that
frame's last executed address, but I don't think that they were ever set
in CurrentLineSection anyway. Once #3192 gets resolved, I can figure out
whether these new fields are actually needed, but I'm not optimistic
about it =)
