 Dear GEOS maintainers,

 Thanks for this great software!

 I would like to file a bug spotted via Valgrind while loading the R rgeos
 package. Below are the steps to reproduce it.

 === Create an R script "load_only.R" to attach the package
 > require("rgeos")

 === Run and debug the script using Valgring (Bash Shell)
 $ R -d "valgrind --leak-check=full --show-reachable=yes --leak-check=full
 --leak-resolution=high --show-leak-kinds=all --errors-for-leak-kinds=all
 --log-file=logs" -f load_only.R

 Valgring reports the following about the leak (I sanitized some paths
 marked as SANITIZED_PATH and R-LIB_PATH):
 40 bytes in 1 blocks are definitely lost in loss record 31 of 2,297
