Hi all,

I have run into a problem using st_StraightSkelton() where it appears to 
hang at 100 cpu. Maybe an endless loop?

select st_straightskeleton('POLYGON((256 760,518 760,518 630,674 630,674 
239,673 239,127 239,127 240,126 240,126 513,127 513,127 514,126 514,126 
630,255 630,256 630,256 760),(128 629,128 423,270 423,270 422,271 
422,271 240,672 240,672 629,128 629),(258 759,258 631,516 631,516 
759,258 759),(128 421,128 240,269 240,269 421,128 421))'::geometry);

POSTGIS="2.3.3 r15473" GEOS="3.5.1-CAPI-1.9.1 r4246" SFCGAL="1.2.2" 
PROJ="Rel. 4.9.2, 08 September 2015" GDAL="GDAL 1.11.3, released 
2015/09/16" LIBXML="2.9.3" LIBJSON="0.11.99" RASTER

Can anyone reproduce this?
Any idea how to work around it?

Is there a non-CGAL version of skeleton?

Thanks,
   -Steve
