[GRASS-dev] r.fill.dir segfaults on large maps.

[Isaac Ullah]

Hmmm... I restarted GRASS and I can no longer replicate the problem. It was
a very specific cut-off at 150 million cells though. I guess it's a
non-issue since it works now. I monitored the memory usage, and even at 400
million cells, it was only using 52 MB. Strange why it was breaking before!
Thanks for your help though.
