Hi,
With the release of gdal 3.4.2, gdalbuildvrt seems to have a bug when selecting
image bands. It works OK when band 1 is specified but if other band(s) in the
image are used without band 1 then it seg faults. I noticed there were some
changes around checking bands in the release notes "change logic to check
homogenous number of bands” and I had a quick look at the commits but cannot
see where this is occurring.
# Works:
gdalbuildvrt test.vrt sen2_20210527_aber_subset.kea -b 1
# Seg Faults:
gdalbuildvrt test.vrt sen2_20210527_aber_subset.kea -b 2
ERROR 5: sen2_20210527_aber_subset.kea: GDALDataset::GetRasterBand(2) - Illegal
band #
Segmentation fault (core dumped)
# Works:
gdalbuildvrt test.vrt sen2_20210527_aber_subset.kea -b 1 -b 2 -b 3
# Seg Faults:
gdalbuildvrt test.vrt sen2_20210527_aber_subset.kea -b 2 -b 3 -b 4
ERROR 5: sen2_20210527_aber_subset.kea: GDALDataset::GetRasterBand(4) - Illegal
band #
Segmentation fault (core dumped)
Note, the input image I was using has 10 bands and these commands work with
3.4.1. I get the same seg fault on Mac, Linux and Windows ("Windows fatal
exception: access violation").
Many thanks,
Pete
