--- Comment #2 from Xisco Faulí <xiscofauli at libreoffice.org> ---
Trying to reproduce it, I found sometimes it hungs and sometimes not and I
found a reliable way of reproducing the hang:

1. Launch LibreOffice in safe-mode: instdir/program/soffice --safe-mode
2. Open the document -> It doesn't hang
3. Go to sheet COST -> it hangs

Make formula group weight take number of cells referenced into account
And not just the number of rows in the group. This means that even
relatively short formula groups that calculate over large ranges of
cells will be eligible for parallelized calculation. The weight of a
formula group is the number of rows in the group times the weight of
the formula.

The weight of a formula is for now the number of cells referenced by
all cell ranges in the formula, divided by 10. For instance, the
weight of SUM(A1:B100) would be 20. If no cell ranges are used, the
formula's weight is one.
