[argyllcms] Scanin generates .ti3 file gigabytes in size

Hi,
I was trying to create an ICC camera profile from a CC24 passport and am
observing a weird behavior where scanin output gets stuck and the resulting
.ti3 file keeps growing endlessly. It reached 12Gb when I terminated the
program. The diag.tiff meanwhile is only 8 bytes in size. I'm doing this all
under macOS Big Sur.
The command I use is the following (CC24Classic.cht comes from ArgyllCMS):
scanin -v -dipn -G 1.0 chart-raw.tiff CC24Classic.cht CC24Classic-D50.cie
The output:
Input file 'chart-raw.tiff': w=8288, h=5520, d = 3, bpp = 16
Data input file 'CC24Classic-D50.cie'
Data output file 'chart-raw.ti3'

The chart-raw.tiff was created using this command (dcraw is 9.28 from homebrew):
dcraw -v -T -o 0 -j -M -6 -W -g 1 1 -w -c _DSC0394.NEF > chart-raw.tiff
What could be relevant is the fact I measured a Color Checker Classic manually
using iStudio (Colormunki) device. I'm not sure whether I got the layout right,
but I started with the Dark Skin patch, considering it A1, moved horizontally
to Bluish green (A6) and then similarly through each subsequent row with the
grayscale being the last one. I measured patch by patch, here is the command:
chartread -v -H -p CC24Classic
Then I generated the reference file:
spec2cie -v -i D50 CC24Classic.ti3 D50-reference.cie
At this point the issue with scanin occurs. Please comment whether I'm doing
something wrong.
