I wouldn't be surprised anything random happens when --first-parent
is used together with simplify_merges(); the function needs full
analysis of all commits in the specified range, and first-parent
traversal specifically tells us not to descend into other parents.
It might not be a bad idea to forbid this combination when the
command line options are parsed.

What information were you trying to get out of the above command?
