Can you send me the output of:

tar -cvf /tmp/test.tar /usr/ports/devel/nspr/work/nspr-4.9/mozilla/nsprpub/build/dist/lib/../../pr/src/./libnspr4.so.1

(A tar archive containing only that one source file.)

This looks similar to a bug that we found in libarchive recently
I didn't think that bug impacted FreeBSD, but I may have been
wrong….  if it did, it will be obvious from the structure of the
created archive.
