Hello Lars, Hello Olivier;
I have a suspicion that this may be with the initializer list; I do not have VS2013 handy.
However, without initializer list and using push_back(), it compiles and runs without crash on both VS2010 and mingw gcc 3.4.2. Could you try that maybe?
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.
Probably related to this: it's appears to be a known (and pretty serious IMO) bug in the compiler. http://connect.microsoft.com/VisualStudio/feedback/details/800104/ The report has to do with CString, but an SO blog explains how the compiler is treating temporaries. http://stackoverflow.com/questions/19269345/initializing-map-of-maps-with-in... Plausible workaround: avoid initializer lists, especially of VS20XX is your target. Other than that, HTH and good luck.
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.)

Care to define "crash"?
If the compiler "crashes" (i.e. access violates; internal compiler error et. al.), then it is always a compiler bug; A compiler shouldn't choke on the input.
It seems to be a runtime failure during post-main shutdown, not an ICE.
