A simple patch is to comment out the performance tuning with fromIdx in
ColumnInfoRecordsAggregate.groupColumnRange(short fromColumn, short toColumn,
boolean indent). It does not work because the column records are NOT ordered by
column no:
// taken from 3.1 FINAL
org.apache.poi.hssf.record.aggregates.ColumnInfoRecordsAggregate:
public void groupColumnRange(short fromColumn, short toColumn, boolean
indent)
{
...
// OD bug fix: records NOT ordered by column no
// fromIdx = columnIdx - 1; // subtract 1 just in case this
column is collapsed later.
...
}

fixed in svn 694534.
As you pointed out, the ColumnInfoRecords were not being kept in proper order.
Rather than disable the optimisation, I fixed the logic to keep the records
sorted. There were a few other methods besides groupColumnRange() that relied
on proper ordering.
Junit added for groupColumnRange() and collapseColumn()/expandColumn()
