GDALBuildOverviews fails if .rrd exists

Reported by: rblazek Owned by: Even Rouault
Priority: normal Milestone: 1.9.2
Component: GDAL_Raster Version: 1.9.1
Severity: normal Keywords:
Cc: rblazek

Description

If GDALBuildOverviews() is called on a dataset which has already .rrd file, the .rrd file is deleted, overviews are not created but GDALBuildOverviews() returns CE_None. Next call to GDALBuildOverviews() without reopening the dataset causes crash somewhere in GDAL. It seems that poBand in GDALDefaultOverviews::BuildOverviews() is somehow corrupted or even wrong pointer and calling its methods is causing crash.

This was observed in QGIS, but the first part (not creating overviews) can also be reproduced with gdaladdo.
