Hello Wim, That's right. The problem was in boost 1.48. although I didn't use codecvt_facet.
Now, with boost 1.49. application works fine. Best regards, Marin. "Wim Dumon" je napisao u poruci interesnoj grupi:CAJ2=PVSn1VEb5oma=m=+NY0gheb_OUabo5mQXTArd+1_A3=a...@mail.gmail.com... Hello Marin, It looks like the conversion inside boost.filesystem from std::string to std::wstring crashes. Neither the in or out pointer for the strings are null, yet you get a violation for reading out NULL. Could it then be the codecvt facet which is null? Did you modify the C++ locale? A quick google led me to believe that you ran into this bug: https://svn.boost.org/trac/boost/ticket/6320 Best regards, Wim.
