[cgal-discuss] segmentation fault, 2D Delaunay triangulation, 3.4 and 3.5-beta1

Hello all,

I'm using a CGAL to do 2D Delaunay triangulation and I'm getting segmentation
faults triggered by the "orientation" function in "march_locate_2D" on line
1969 of Triangulation_2.h, called by me calling "insert" to add a new vertex.

The fault are not consistently reproducible - only appearing about 1 in 5-10
times that the executable is run. It happens with both the
Exact_predicates_exact_constructions_kernel and
Exact_predicates_inexact_constructions_kernel, and whether it is a debug
build
or not.

Compiling on linux x86_64, gcc 4.3.3 with -DFULLDEBUG -O0 options and boost
1.39.0, the error message is below and attached. I get the same result using
CGAL 3.4 and 3.5-beta1.

Any suggestions?

Best regards,

Graham Macpherson
