[GRASS-user] r.proj error

[gary]

I've compiled Grass 6.1. The r.proj at the lower resolution worked fine 
(Hamish's tip to prevent a 80GByte file!). The r.los bombed. Here are 
some of the warning messages:
------------
WARNING: segment_seek: Invalid argument
WARNING: Failed seek in segment file for index = 240605900 n = 12 at
          col:row 0:201054
WARNING: segment_seek: Invalid argument

WARNING: Failed seek in segment file for index = 240876632 n = 12 at
          col:row 0:201057
-----------------

I compiled this with and without  the 64 bit flag. [System is AMD 64 
4400 running Suse 10.0]  The problem is the same, i.e warning messages 
and no output. My compilation does does not have fftw installed, if that 
makes a difference.

Any ideas?
