There must be something fishy here. See for example our test results here:

https://cgal.geometryfactory.com/CGAL/testsuite/results-4.13-I-34.shtml

You'll see that the line Surface_mesh_Examples where sm_circulators.cpp
is tested can be compiled and ran successfully on all our test platforms
(that includes some of yours).

Note also that in your compilation line with gcc you are missing 
-frounding-math but that should not be responsible for the issue you have.

Could you indicate the gcc version with which sm_circulators.cpp is
failing?

Sebastien.
