This bug has been fixed in Commit 14651f94c7 (any Gnuastro version later than 0.13.9).

Segment's labeled images will now be thread-safe (reproducible when run in multiple threads). See the commit message for more details.

To use this feature you can get the most recent tarball (which has fixed this bug) from this address: http://akhlaghi.org/gnuastro-latest.tar.lz (it will be in the official gnu.org servers with version 0.14, probably in a few months).

When Segment is run on multiple-threads, its finally set labels become different. But the output should not depend on the number of threads, and this should be fixed!

Until its fixed, a work-around is to run Segment on a single thread.
