[postgis-devel] Build warnings on trunk: "array subscript is above array bounds"

[Mark Cave-Ayland]

Hi all,

I get the following rather worrying warnings when building SVN trunk:

(cut)

gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith 
-Wdeclaration-after-statement -Wendif-labels -fno-strict-aliasing 
-fwrapv -g -fpic -I/home/pg90/rel/include -I/home/pg90/rel/include 
-I/usr/include/libxml2 -I../liblwgeom -I../libpgcommon -I. -I. 
-I/home/pg90/rel-9.0.7/include/postgresql/server 
-I/home/pg90/rel-9.0.7/include/postgresql/internal -D_GNU_SOURCE   -c -o
