</div><div>It's really simple to reproduce the problem : do a "buildvrt" on a set of raster ( > 1 raster ). Edit the vrt file and rename "ComplexSource" tag with "KernelFilteredSource". add if you want the kernel definition.</div>
<div>Now you can do a gdal_translate to write a tiff file.</div>
<div> </div>
<div>There's no error in the terminale.</div>
<div>gdal_translate crash and a windows error dialog appears saying that the the program has encountered an error and have to be close (the error is in frensh sorry for my bad english...).</div>
<div>I'm using gdal 1.9 x64 onto Win 7 x64.</div>

<div>It's the same probleme, gdal_translate crash. But if the VRTRasterBand have just one KernelFilteredSource element, gdal_translate work fine and apply the filtre correctely.</div>

<div>The poblem appears if there are more than one KernelFilteredSource element in the VRTRasterBand.</div>

<div><br>It's work fine with a gdal_translate.<br>Now I want to apply a filter kernel to the VRT. I have to use the KernelFilteredSource.<br>The gdal api say that VRTKernelFilteredSource is a sub-class of VRTComplexSource. So a VRTKernelFilteredSource <b>is </b>a VRTComplexSource.<br>
But if I replace VRTComplexSource by VRTKernelFilteredSource, gdal_translate crash. This is the new VRT :<br><br>
