I don't see how that is an issue because one entry is to be used for the
breakpoint location (at a specific column) while the other one is not to be
used for a breakpoint location.
It looks like you are not printing out the column info from what is read in
from the dwarf either.
Looking at the original `.loc` at that is on the same address:
```
.loc 1 8 5 view .LVU1
.loc 1 8 23 is_stmt 0 view .LVU2
mov x0, 0
.LVL1:
.loc 1 8 23 view .LVU3
```
Note for the first address, the first line info is column 5 while the second
one is column 23. Yes both are line 8 but different coumns. And then you have a
second line info for :8:23 which does not have is_stmt set.
