v.surf.rst memory problems

[fpachecouy]

On Ubuntu 9.04, GRASS 6.4 (from deb packeage) and GRASS 6.5 (svn).

When I run v.surf.rst with valid parameters program crash with this output: v.surf.rst tension=80.0 input=curvas elev=curvasMDT scolumn='cota' segmax=100 dmin=50 Percent complete: Reading lines from vector map ... Reading nodes from vector map ...

* glibc detected * v.surf.rst: munmap_chunk(): invalid pointer: 0xb7f85e60 *

Output (using valgrind): valgrind v.surf.rst tension=80.0 input=curvas elev=curvasMDT scolumn='cota' segmax=100 dmin=50

Thanks. Fernando.

Fernando - you are missing zcolumn for the values to be interpolated but you are defining scolumn for the smoothing values. I will change the priority to normal - the code should recognize the user mistake and let him know that zcol is missing. If your data are 3D and the value to interpolate is the z-coordinate then you need to define layer=0. I have the code modification with -z flag instead of layer=0 for this case, I just did not have time to submit.

Great. It was my mistake. Sorry.

I will try to use the 3D option. Thank you very much.
