    Description

      When using version 6.6.0 we have a crash when creating an image from a bytearray.
      and precisely

      • within QSvgTinyDocument::load(const QByteArray &contents) .
      • at line 199 QSvgHandler handler(&buffer);

      We had no problem with any previous version of QT.
      Inspecting the code I have seen that the code in the function QSvgTinyDocument::load has completely changed from version 6.5.3 to version 6.6.0.

      Sorry I don't have currently time to investigate further.  For the moment here some printscreen regarding the call stack.

      New function 6.6.0

      Previous implementation 6.5.3
