EHsc is important, there is no crash without it. 

icl /Qm64 /EHsc hevcehw_base_packer.cpp

hevcehw_base_packer.cpp(17): internal error: access violation
std::unique_ptr<PackedHeaders> ph = std::make_unique<PackedHeaders>(PackedHeaders{});

#include <memory>
#include <map>

struct PackedData
{
    std::map<unsigned, unsigned> PackInfo;

struct PackedHeaders

Hi Alexandr,


Thanks for reporting this to us.

We have observed similar behaviour too.

We will be escalating this to our internal team.

As a temporary workaround, we found that when you re-arrange the struct variables inside PackedHeaders we haven't gotten any error.

Like this:

struct PackedHeaders

  PackedData Bar;

  PackedData Foo[2];

};
