[Qgis-developer] QGIS for Windows 64bit crashes when using addSttributes on any vector data provider

Hi Luca,
the code is as simple as creating a memory vector layer, populating a list
of QgsField and passing the list to addAttributes method of the provider.
It was a simple example for the course.
Generally I set the attributes one by one through the layer, inside an
editing session  This works fine. But addAttributes works only on 32bit.

For curiosity, can you post the code of the bug?

Some day I tried to use addAttributes, but I found that using
initAttributes/setAttrobite makes QGis more stable.
