What should I do to solve this error in Qvector?

As @Christian-Ehrlicher & I have suggested, maybe you should really be down-sampling to reduce your data points.

Having said that, if you are saying that a properly-compiled 64-bit now bombs out in the same way as 32-bit at what we think is only half a gig of so of memory on a machine with plenty of free RAM, something sounds wrong there. You could do some more investigations on the machine, seeing how much you are really allocating and how much free memory you are able to access. I would want to understand that before I figured what I need to save away to file or whatever.

earlier I was doing mistake while creating 64 bit application version. I am using visual studio while creating 64 bit application I was just copied all setting of 32 bit application, So That in Solution platform it was showing x64 but it was creating 32 bit executable file.

I created 64 bit application version, which is save very large amount of data in RAM.
