Unknown crash in ocl.cpp

edit

I have an application that, ten minutes ago, was compiling and running perfectly. Now, it will not run, crashing on this line:

g_isOpenCLAvailable = ::clGetPlatformIDs(0, NULL, &n) == CL_SUCCESS;

in the file:

modules/core/src/ocl.cpp

I am not using OPenCl, nor have I ever in this project. What could be going on here?

Thanks.
