Build pyramid crashes for this TIFF attached

Reported by: yanchen Owned by: warmerdam
Priority: high Milestone: 1.5.3
Component: GDAL_Raster Version: unspecified
Severity: normal Keywords: build pyramid HFA
Cc: swoo@…, gaopeng


Inside HFADataset::IBuildOverviews function, ::GetRasterBand?() returns a NULL pointer for 2th band. Number of band is not correct.

When I debugged into HFAGetRasterInfo(), I found when .aux is read, hHFA->nBands is equal to 1.

It would be helpful to know what function, and arguments were used to create the overviews. I'm guessing some override config options are used to force use of aux/rrd overviews instead of TIFF overviews. Is that right?

In experimenting with this file, a problem was identified with EXIF IFD handling in libtiff 4. A distinct bug in the libtiff bugzilla has been created for this issue.

I do not believe this is related to the problem you have encountered though, since I gather you are forcing HFA/AUX/RRD overview building.

Problem reproduced using the command:

 gdaladdo --config USE_RRD YES DigitizingFeatures.tif 2 4

The problem has been corrected in trunk (r14902) and 1.5 branch (r14903) by not accepting .aux files that have a different number of pixels, lines or bands than the dependent dataset in the findauxfiles function.
