That would do the trick, I just completed my testing and pushed to the
master branch on kernel.org and github, tests detailed at:

https://git.kernel.org/pub/scm/devel/pahole/pahole.git/commit/?id=040fd7f585c9b9fcf4475d294b3f5ddf78405297

There are some minor bug reports I want to address but my ETA right now
is the end of this week to release v1.19.
