That's curious, did he give a reason? You can have an accelerator table for
a final executable. That said the accelerator tables make not sense for
-gline-tables-only which could be causing you the problems you're see since
there's very little info for the tables to work with and there could be
issues there. There should be a DIE for each entry in the names table. What
do, for example, those offsets give you?

Not surprising as it's pretty heinous debug info at this point. So, what
are the DIE offsets for those functions? llvm-dwarfdump doesn't dump them
at the moment so you'll need to use dwarfdump to look for the functions.
