FINAL RESULTS:
data/r-cran-rgdal-1.5-18+dfsg/inst/include/projects.h:92:11: [3] (buffer) getenv:
Environment variables are untrustable input if they can be set by an
attacker. They can have any content and length, and the same variable can
be set more than once (CWE-807, CWE-20). Check environment variables
carefully before using them.
