"definitely lost" memory leak in rgeos_Init (rgeos.c:57)

[philae]

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

The R session data is:

packageVersion("rgeos")

[1] ‘0.3.15’

xxx <- sessionInfo()
xxx$R.version$version.string

[1] "R version 3.2.3 (2015-12-10)"

xxx$platform

[1] "x86_64-redhat-linux-gnu (64-bit)"

For reference, this was marked as invalid because related to rgeos which is handled in ​https://r-forge.r-project.org/projects/rgeos/

Hello,
Thanks for the information, I've replied to Roger at the appropriate channel. Maybe it will end up to geos-devel mailing list too.
