I am running the following threaded code which is throwing only in the debug build. The source of the error is in the memory stack. Which is indicating that allocation and release size of memory don't match (see below). If I swap the use of cv::cuda::HostMem dst for cv::cuda::GpuMat dst. The error goes away.
Can anyone explain why?
//-----------------------------------------------------------------------------
//-----------------------------------------------------------------------------
void RunCalcSum()
{
cv::cuda::GpuMat src = cv::cuda::GpuMat(cv::Mat::ones(100, 1, CV_32S));
cv::cuda::HostMem dst;
cv::cuda::calcSum(src, dst);
}
//-----------------------------------------------------------------------------
//-----------------------------------------------------------------------------
void RunFindMinMax()
{
cv::cuda::GpuMat src = cv::cuda::GpuMat(cv::Mat::ones(100, 1, CV_32S));
cv::cuda::HostMem dst;
cv::cuda::findMinMax(src, dst);
}
