[GRASS-dev] G_get_raster_sample: memory corruption

Hello list!

I am hunting after a bug in my program which causes a memory corruption in 
the functions called by G_get_raster_sample. See backtrace and memory map 
below for details.

The arguments passed to G_get_raster_sample appear to be valid.

Any hints what the problem might be?

Thanks in advance,
Florian

z = G_get_raster_sample( fdrast, &window, NULL, y, x, 0, method );
