Hum, it would be useful if you could subset the input file to the
minimum needed to reproduce the error and (possibly privately) share it
to me.

Can I do other useful tests tonight?
Maybe just check/confirm that the issue is multithreading on the
decoding side (which it looks to be) with:
gdal_translate web_mercator.tif web_mercator_jpeg.tif -co COMPRESS=JPEG

- the "corrupted double-linked list" is definitely a proof of either a
bug, or a mis-configuration. This is a message we see sometimes when
GDAL accidentally links against 2 different libproj. Can you check "ldd
/path/to/libgdal.so" to see if there is not
Hi
I am warping a file to EPSG:3857 and later generating a COG with JPEG
compression.
The input tif file has also JPEG compression. (I learned that I need the -
