Comment (by angerman):

 > Each data section is 2 byte aligned. If it would end on an odd offset, a
 newline ('\n', 0x0A) is used as filler.
 (from [https://en.wikipedia.org/wiki/Ar_%28Unix%29 wikipedia:ar (Unix)])

 That's pretty much what the `Ar` module fails to account for.

 For some reason `libHSbase-4.11.1.0.a` ends up having odd byte long object
 files. As such parsing the archive falls apart.
