[GRASS-dev] r.flow: crash on 64bit

Mon Jan 29 16:39:18 EST 2007

Hi,

when using r.flow on 64bit, it crashes (Spearfish example):
r.flow elevation.dem flout=flout lgout=lgout dsout=dsout
Reading input files: elevation
Precomputing: tangents
Precomputing: e/w distances
Precomputing: quantization tolerances
Precomputing: interpolated border elevations
Precomputing: aspects
Calculating maps ...
Segmentation fault

It dies in calc.c:223.

A backtrace:
