tdf#66141: SwTxtFrm::FormatQuick(bool) endless loop
|
|
|
|
If a line happens to be invisible (e.g. in too thin cell of a table)
|
|
then aLine.FormatLine(nStart) returns nStart, and
|
|
aLine.Insert( new SwLineLayout() ) is executed until OOM.
|
|
|
|
keep the zero advance loop detection attempt, but allow the first
|
|
insertion and disallow subsequent inserts
|
|
|
|
