Access violation writing location

asked 2015-07-07 12:38:02 -0500

I am using opencv 3.0.

Majority of all the samples are working fine but some programs runs build successfully but it do not execute with output and it exit with this message

Unhandled exception at 0x000007F80B966613 (igdfcl64.dll) in ConsoleApplication1.exe: 0xC0000005: Access violation writing location 0x00000000B43CC190.

Here is the code for it. please guide me what is wrong with my code.

    #include "opencv2/objdetect.hpp"

            break;

no problem with the code.it might be a driver problem. google "igdfcl64.dll" you can see some issues like this

@sturkmen I have the same trouble with igdfcl64.dll. Latest drivers are installed. Is there a known solution to this problem? HP Elitbook Folio9470m Windows 10 x64
