I have the same problem.

In osgeo4w on Vista, each gdal16 .exe crashes before
it had finished, producing anyway a correct result.

Under Seven there seems to be a gdal_tools plugin problem for the merge

In gdaltools-plugin, Merge tools works fine but it calls the
gdalinfo.exe to get the input files' extents.
The error is due to the gdalinfo.exe crash and the merge's
"use intersected extents" option will never be enabled.
