Regarding packaging of pahole:
What is the state of the contained ostra-cg?
I have no clue what it is and how to use it. Is there still a use-case
for it?

Starting it without arguments only shows the usage string.
Running it with two dummy arguments:
$ ostra-cg x y
Traceback (most recent call last):
File "/usr/bin/ostra-cg", line 404, in <module>
class_def = ostra.class_definition(class_def_file = "%s.fields" %
traced_class,

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/share/dwarves/runtime/python/ostra.py", line 154, in __init__
f = file(class_def_file)
^^^^
NameError: name 'file' is not defined. Did you mean: 'field'?

According to
https://stackoverflow.com/questions/32131230/python-file-function the
function file() does not exist in python3.

This part could be fixed by replacing it with open() but I wonder if
this is worth it.

As nobody has complained about it being broken:
Should ostra just be removed?
