#1906 new enhancement

Raster "title" longer than 100 characters segfaults ps.map -- Request to extend the field's capacity.

Description (last modified by martinl)

The "title" of a raster map is part of ps.map's "header" instruction. Defining a title to a raster map (r.support) with more than 100 characters, causes a segfault when trying to draw this map with ps.map.

Tested using data from the "spearfish60" Location in both G6 and G7, e.g.:

# under G7 -- set a low resolution for a quick test!
g.region res=1000 -pa

# define raster "title"
r.support landcover.30m title="123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789"

# ps.map-it
ps.map --v in=spearfish_landcover_30m.psmap out=spearfish_landcover_30m.ps
