Hi,
Given OP's test case and replacing the vector initialization with three
calls to push_back (or emplace_back, no difference) the program does not
crash on shutdown.

I forgot to mention the address that the access violation triggered on
in my repro run is "Access violation reading location 0xCCCCCCD4.", so
an offset into "uninitialized stack memory" it seems.

(Also note that the Boost list doesn't do top-posting, replies go
in-line after the sections they refer to.)
