Marking an issue as a "serious bug" without giving enough
material for reproduction nor diagnosis tends to discourage
people from looking into it seriously, as the issue cannot be
even judged if it is really serious.  For example:

  You mean git cat-file commit ... ?
  I get the normal output, but the problematic commits don't show a
  newline character at the end of the cat-file output.

"I get the normal output" is not what Alex asked you to supply,
nor would be sufficient information.  There may be some
abnormality in the commit object that you probably did not spot,
but Alex or other people may have been able to if you were
actually posted its output here.

I have been suspecting that there is a NUL in the middle of the
message somehow (I know the lowest-level plumbing commit-tree
allows any byte sequence in the log message if you worked hard
enough), which the parser is not prepared to cope with, but we
haven't seen enough evidence to support nor refute that theory.
We do not have much to work from.

One thing I noticed funny in your original message was "-1-".
Is it essential that the number is spelled incorrectly to
reproduce this problem?

  $ git rev-list -1- --pretty=format:"%s%n%b"
