[gdal-dev] Error trying to merge 3 files for a multi-band ( Windows 7 PRO,

[Even Rouault]

Eduardo,

Yes, this is a known regression.  See http://trac.osgeo.org/gdal/ticket/3354

You can workaround this by specifying the -q or -v flags.

Or just download 
http://trac.osgeo.org/gdal/browser/branches/1.7/gdal/swig/python/scripts/gdal_merge.py?format=raw 
and use it as the replacement for the one from FWTools.

Best regards,

Even
