Possible problem in file raster/rt_pg/rtpostgis.c line 471

[petrum]

While experimenting with a novel static analysis technique in CodeSonar, we noticed the following potential problem at the next location:

FilePath: raster/rt_pg/rtpostgis.c Function: _PG_init Line number: 471

If the POSTGIS_ENABLE_OUTDB_RASTERS variable is set to the empty string, the result of getenv will be deallocated at the indicated line (which is forbidden according to the specification of getenv).

Thanks, Petru-Florin Mihancea
