Summary: problem with r.what at the longitudinal edge
Issue type: module bug
Issue status: None
GRASS version: 6.2.1
GRASS component: raster
Operating system: Linux
Operating system version: Fedora Core 6
GRASS CVS checkout date, if applies (YYMMDD): 070414
Initial Comment:
I get null '*' value when specifying longitude edge with grass6.2.2cvs (20070414) compiled with Fedora Core 6.
r.what input=mod12 east_north=180W,55N
** note ** 180W 55N is outside your current window
180W|55N||*
If I change r.what/main.c as in the attached file, I get
r.what input=mod12 east_north=180W,55N
180W|55N||0
I assume this is related to Fedora Core 6's compiler bug or optimization thing. However, I think it is safe to cast the dcol to int in this case.
Here is my system information.
