First-chance exception in stitching OpenCV 3.0

edit

Hi,

I want to use opencv 3.0 download from link in opencv.org with cmake. I have make a small video and all file can be downloaded from here. Program is OK until I press return to close it with this error :

R6025
- pure virtual function call

it seems that's a problem with VS 2013 win 64 to have global Mat variable. If I move this variable in local It's ok.

Now in debug I have got a first chance exception :

First-chance exception at 0x00007FF9BABEA1C8 in myProject.exe: Microsoft C++ exception: cv::Exception at memory location 0x000000839B28AC40.

It happens in fundam.cpp between line 173-174.

I don't think it's a very important because program still gives good result but if somebody know how to suppress this exception it would be pleasant in this configuration
