The maintainer is not really responsive. I skimmed the code and
it seems it only calls (indent-according-to-mode) and stuff,
and does not do anything crazy:

https://github.com/Malabarba/aggressive-indent-mode/blob/master/aggressive-indent.el

Would you agree that if the code does only automatic indentation
for the user by calling core indent functions then it's likely
that emacs is the culprit for the error and I should submit
a bug report  for emacs?

The problem is reproducible and it only requires installing
aggressive-indent-mode which is in GNU ELPA.
