[Boost-users] [random_device] App crash on boost::ramdom::random_device

Hi there! My app crash on customer's site. It crashes everytime the app is starting. It happens on Chinese Windows7 (64bit) OS but it runs well on my PC with Korean Windows7 OS and English Windows7 OS. My app is built on VisualStudio 2010 (x86 build, C++) using websocketpp library and boost 1.55. The call-stack from the dump file shows my app(TMSClient100) called websocketpp::endpoint, then it called boost::random::random_device then ThrowException. Here's the call-stack info: 14 001cf6ac 7113872d e06d7363 00000001 00000003 KERNELBASE!RaiseException+0x58 15 001cf6e4 713b7c5a 001cf704 713d9350 b621b77b msvcr100!_CxxThrowException+0x48 [f:\dd\vctools\crt_bld\self_x86\crt\prebuild\eh\throw.cpp @ 157] 16 001cf814 713b7da3 001cf840 b621b9a7 002a19bc TMSClient100!boost::random::random_device::impl::error+0x15a 17 001cf8b8 713b7f7b 001cf8dc b621b94b 00000000 TMSClient100!boost::random::random_device::impl::impl+0x143 18 001cf904 71383901 b621b8ab 001cfac4 002a17e8 TMSClient100!boost::random::random_device::random_device+0x8b 19 001cf928 7137eb2c 002a17e8 b621b8ef 001cfac4 TMSClient100!websocketpp::endpointwebsocketpp::config::asio_client,websocketpp::config::asio_client>::endpointwebsocketpp::config::asio_client,websocketpp::config::asio_client>+0x191 [d:\dev\tms\trunk\library\library_c++_3\websocketpp\websocketpp\endpoint.hpp @ 101] 1a 001cf96c 713598c2 002a1790 b621b83b 001cfa08 TMSClient100!TMS::CWebSocketClient::CWebSocketClient+0x9c [d:\dev\tms\trunk\library\library_c++_3\tmsclient100\websocketclient.cpp @ 15] 1b 001cf9b8 010316cd b620327e 00388fa8 0103c908 TMSClient100!TMS::CTMSClient::CTMSClient+0xf2 [d:\dev\tms\trunk\library\library_c++_3\src\tmsclient.cpp @ 25] Any suggestion how to debug this problem will be greatly appreciated.
