I'm assuming that's a typo and you meant 0xC000005, which is an access 
violation.  Typically this means that something wasn't initialized properly.

Boost 1.60 is ancient history; you should consider upgrading.

Since you've narrowed the trigger down to a particular header, you can 
try narrowing it further by commenting in/out things in that header.  Or 
post a full compilable MCVE if you want help.

But the most likely problem is that you have an ODR violation -- some of 
your code is being compiled with different settings than others, which 
causes incompatible compiler output.  The most common culprit for this 
sort of thing is incompatible #pragma pack or #define settings, but 
there are other possibilities.

In particular you should not include external headers under the 
influence of a non-default pack setting (whether via #pragma or 
project/file settings) -- if you must use a different value then keep it 
to as narrow a scope as possible.
