[GRASS-user] r.li help

[William Kyngesburye]

Here's an interesting clue (or maybe a completely different problem) -  
our previous crash was run 64bit.  When I force the 32bit binary to  
run with arch -386 (OSX-only command) I still get lots of:

WARNING: Unable to open header file for raster map <@(null)>
CHILD[pid = xxxxx]: unable to open mask ... continue without!!!

but no illegal filename errors and no crash and all the workers  
processes complete.  I don't know what the output is supposed to look  
like, but the raster looks sensible.

I'll try poking around with some debugging.  Maybe a bug report is in  
order also?
