Crashes QGIS or corrupts data: Copied to github as #:13984


When I apply the interpolation plugin on a shapefile of 1.7M points, i get a segfault.
Looks like a stack overflow in gdb. Stack is full of DualEdgeTriangulation::doSwap/checkSwap frames (~140000 frames). Stack pointer looks pretty magic: ebp at 0xbf800068
I can provide the shapefile (~50MB) for testing on request.
