[mapserver-users] bad query result crashes Perl

[Mr. Puneet Kishor]

I query Pg to grab the data with which I construct LAYER CLASSes like so (nothing fancy).

    SELECT class_name, class_expression, class_color FROM table;

A few of the rows in the result set come back with class_color = '' (I can easily avoid those, but that is not the point of this post). The "bad" color crashes mapscript.bundle which takes down Perl as well, which should never happen.

I am using Perl 5.14.1 on Mac OS X Lion.

$ perl -V
