CGAL users discussion list

[Marcos Dione <>]

    I'm using PostgreSQL 9.5 + PostGIS 2.2.2, the latter in its turn uses
libsfcgal 1.3.0, which in turn uses libcgal 4.8.1 (all this under Debian
Sid). Today, the attached query failed with the following message:

CGAL failed to create straightSkeleton

    I managed to work arround the issue by pre simplifying the Polygon.
I'm not sure why the query is failing, and I can't find in CGAL's docs
when or how do they report errors (I guess they just return a null
pointer).

    Is this the right place to report this, or should I first try to go
down the stack? As you can see, it's quite deep (I'm even using
python-shapely 1.5.16 on top of all that).

    Cheers,

        -- Marcos.
