 Hi Community,

 I wanted to use r.thin on a raster map before r.to.vect on the result but
 r.thin crashes after 84 passes every time. Smaller number of iterations
 run without any problems. I was able to reproduce the error by using
 r.thin on the elevation.dem from the Spearfish data set. The following
 error is printed to the console.

 {{{

 Any Ideas what might be going wrong?
