GdalWarp bug - missing pixel lines for img output

Description
I used gdalWarp of version 1.7.0b2 (FWTools 2.4.7) for retrieving an img file from an vrt file. The bug occurs only for certain data (it seems only with a certain minimum size). The resulting img file has missing horizontal pixel lines either in the middle or on the bottom. When I use gdalwarp version 1.7.0dev (FWTools 2.4.6) on the exact same data, the resulting img file is fine. I detected this bug when opening the img file with ArcMap 9.2.

Duplicate of #3458. Was fixed by GDAL 1.7.2. If you have a lot of RAM, you can try workarounding by increasing the -wm parameter.
