Comment 5 for bug 617384

Just to clarify, there's two patches mentioned here:
(1) The performance enhancement patch by Wei Guozhi (that happened to make the GDB test case problem go away)
(2) My patch to fix the underlying bug in generating the wrong line numbers

I'd agree that we shouldn't backport (1) at this stage. However, backporting (2) does make sense to me, since this is a straight-forward low-risk change that simply fixes an obvious bug in debug info without affecting anything else.

Do you agree?
