<br>
On the Linux system where this crashes with QGIS,
could you do :<br>
<br>
gdalinfo -checksum -stats the.tif<br>
<br>
If this crashes, the issue is clearly in GDAL.
Otherwise it is likely in QGIS.<br>
<br>

No crash, but I do see a Warning:<br>
<br>
gdalinfo -checksum -stats kidron_e2.tif Driver:

<br>
Also I have found that creating overlays seems to solve
the problem (?!). After running:<br>
<br>
gdaladdo --config COMPRESS_OVERVIEW JPEG --config
PHOTOMETRIC_OVERVIEW YCBCR --config INTERLEAVE_OVERVIEW
PIXEL -r average kidron_e2.tif 2 4 8 16<br>
<br>
the tiff opens fine in QGIS.<br>
<br>
