-Subject: [PATCH] Fix crash when text contains too many directional chars
-
-In case a text to be layouted contains more than 128 directional characters
-it causes the application to crash
-
-The function initScriptAnalysisAndIsolatePairs() collects information of
-RTL/LTR chaaracters into vector "isolatePairs". The size of the vector is
-capped to 128. Later the function generateDirectionalRuns() iterates
-the text again and tries to access items from the previously capped vector
-above the upper bound.
-
-Task-number: QTBUG-77819
