Hi,

just guessing, but make sure you're using binary compatible versions of built 
Boost libraries and your application.

It could be that you're building your app eg. with _SECURE_SCL=0 (or any flag 
that modifies runtime behaviour) but Boost with _SECURE_SCL=1 (which is the 
default for debug builds). Or vice versa.

That would explain why the crash occurs in the string destructor; you're 
constucting it without additional debug checking (= in your app), but when 
destructor is called (= in filesystem), it expects the additional 
information/members/data to be there (but it isn't) that it tries to tidy.
