@clayborg I am not sure what it means you now accepted the revision? I am still not sure what to do about the tests.

One more thing is that I suppress everything that's called a "warning" here. I tested it, and on our release/optimized binaries (built with gcc) we get lots of "errors" such as:

  00:10:57.048 error: DIE has a start address whose LowPC is between the line table Row[9006] with address 0x00000000033aaf17 and the next one.

  00:10:57.048                  [0x00000000033aaf20, 0x00000000033aaff5))

I am not sure if this was just accidentally called "error" instead of "warning", and we should suppress that as well with `--quiet`, or if this is rather a more severe issue, which should not be silenced. I guess in that case, we would probably update the compiler version to fix that (assuming it is fixed in a more recent gcc version).
