I got the same error on my computer.
This failure comes from a numerical problem since it disappears if you replace,
in both the include and typedef line :

Exact_predicates_inexact_constructions_kernel
by
Exact_predicates_exact_constructions_kernel

Obviously this Delaunay triangulation should not require
a kernel with exact constructions. The problem
is that, as it is coded now, the predicates are not exact
when the kernel are instantiated with Exact_predicates_inexact_constructions_kernel.
Thanks for reporting the bug.

Dear Mariette,
thank you for your prompt reply. Using Exact_predicates_exact_constructions_kernel solved the problem in the testcase as well as in my application.

Best regards,
Eivind LM
