Keith,

Arc/Info binary grid formats requires a directory of files including the
w001001x.adf file.  I would suggest trying to run gdalinfo against the
file to see if the problem is general to GDAL or specific to the way it is
being used in GRASS.

If it crashes gdalinfo then you could either try to debug it via gdalinfo
(if you have the inclination) or you will need to file a bug report
including making the data available.  if the bug is reproducable with gdalinfo
please file the bug report in GDAL's Bugzilla. If it only occurs in the
context of GRASS's r.in.gdal command, you should likely file it against
GRASS.

Best regards,
