Erratic result when sorting a calc column's values containing a formula

[dino99]

Apport also fails to report due to:

Your computer does not have enough free memory to automatically analyze the problem and send a report to the developers.

Thats very strange as only 850 kb/4096 is used at that time, and swap is quite empty.

That crash has happened when 3250/4096 mb was used and swap quite empty: i was getting erratic results when trying to sort a3:bc28 block and wanting to sort ascending the ba column containing a average output calculated on a dozen previous columns containing numbers only.
Looks like there is a very bad memory management.

cat /proc/swaps
Filename Type Size Used Priority
/dev/sdb2 partition 10802172 0 -1

# swap was on /dev/sdc2 during installation
UUID=0a9ca7f0-6eeb-4b21-b70f-670fa600de16 none swap sw 0 0

That sorting issue is also seen with yaketty 64 bits running a gnome-shell session

ok, i've found the reason of that problem: it was inside the complex formula; my bad.
