Possible hint:
It seems that the reported/displayed size matches the value of a 64 bits value
truncated to 32 bits:
expected dec: 108843801799 (correct)
expected hex: 19 5798 9CC7 (correct)
displayed dec: 1469619399 (incorrect)
displayed hex: 5798 9CC7 (incorrect)
** Summary changed:
- ls command reports incorrect file size for large files
+ incorrect size for large files due to possible use of 32 bits instead of 64
bits variable
** Description changed:
Large files are reported incorrectly when using the 'ls' command
- The expected size should 102G instead, it reports 1402M or 2G
+ The expected size should 102G instead, instead it reports 1402M or 2G as if
the size was limited to 2G (32 bits).
Example of INCORRECT size:
$ ls -1 -s --block-size=M
/mnt/f4/plot-k32-2021-05-08-01-15-1648a669ec6edd5cfb124a1512178c5a2a1a714000f4f52b73efc0c3d91a747c.plot

Example of CORRECT size (same file):
$ ls -l
