Description
All of the files in the attached ZIP, except 2.cot which I have included for reference, cause gdal_translate (and other clients of RasterIO) to crash.
Tested with 1.9.2, svn rev 25095, built with VS2010.

The problem seems to be that the GDALRasterBand nXBlockSize and nYBlockSize were being trimmed to the size of the image but when we went to read the blocks for small images we still read for the whole 256x256 size of the intergraph tile.
Fixed in trunk (r25097) and 1.9 (r25098).
Unfortunately, this fix will not make it into 1.9.2, but should be in 1.9.3.
+cc Ivan to confirm my solution.

I've merged this locally and can confirm that it no longer crashes. Thanks.

Frank, The solution is good as is working fine (mpd) but I am wondering if those images can be read by Intergraph's ImageStation and other software and if small images produced by ImageStation can still be supported.
