Intel Inspector: Uninitialized memory access for range loop

Hi all,

I use following Software:

* Microsoft Windows 
* Intel® Parallel Studio XE Composer Edition for C++ Windows* 2016
* Intel Inspector Xe 2016

Following codes cause Uninitialized memory access

std::all_of((uint8_t*)vector_type.data(),

                           (uint8_t*)(vector_type.data() + vector_type.size()),

                           [](uint8_t a) { return 0 == a; })

and

std::vector<uint8_t>(&var_name[2],

                            &var_name[var_name.size() - 60])

var_name.size if bigger than 100.

Can anyone explain me the reason of this error, pls?

WBR,

Dilshod
