[pdal] SegFault with p2g pipeline

[pete.gadomski at gmail.com]

Hello Matthew,




I can't reproduce your results from the information provided. A PDAL+points2grid run works a-ok on my local system.




Can you provide PDAL and points2grid versions? If you're on a Unix-style and have points2grid installed to /usr/local you can do:




    cat /usr/local/include/points2grid/config.h | grep P2G_VERSION_STRING




For PDAL:




    pdal --version




That might help track things down.




Cheers,

Pete
