[Qgis-developer] Exception "Access Violation No RTTI- Data!" on windows XP (32 bit)

[maaza mekuria]

I tried two plugins with a slightly different cose and and I get the same response. I wish it would go away, but wishing does not help here. So I need your expert help.

I find that the canvas object (QgisInterface pointer) loses its data as it passes the layers to processing method. What could cause this? I know the same sort of code works for a single layer data. Any ceiling it has reached? Did I hit the stone/steel wall or am I in need of training. I wish there was an ebook or something that explains these challenges. It would have made my work easier. But I have to be a sleuth and try to find a work around this glass ceiling. 

Any ideas, suggestions?

I am getting the error  "Access Violation No RTTI- Data!"  while I am running my C++ plugin.  I checked out on the web to see what if it was reported by anyone, and I found some references about a year ago. I am not sure if any of you have come across of the same and know why it is due to. The plugin does not crash but I am not able to find out what is causing it. I am opening multiple layer data using the layer data providers (shape file layers on the canvas.)  and nothing more unusual.

The web problems were reported about a year ago and I can not see what was the resolution except the new version seemed to take of it. 
Thank you,

Maaza
