Hi :) I've tried to compile this simple Boost.Coroutine example: #include <iostream> #include void foo(boost::coroutines2::asymmetric_coroutine<void>::push_type& yield) { for (int i = 0; i < 10; ++i) { std::cout << i << std::endl; yield(); } } int main() { boost::coroutines2::asymmetric_coroutine<void>::pull_type coroutine(foo); for (int i = 0; i < 5; ++i) { coroutine(); } } On Linux this works as expected, just as on Windows with Visual Studio. But when I cross-compile on Linux using i686-w64-mingw32-g++ src/main.cpp -lboost_context-mt The resulting exe crashes with: 0 1 2 3 4 5 6 terminate called after throwing an instance of 'boost::context::detail::forced_unwind' abnormal program termination There's a similar problem on StackOverflow: https://stackoverflow.com/questions/45569418/how-to-use-boost-context-correc... But I'm having the crash only with the cross-compiled version, not MSVC. Am I doing something wrong? Or might this be a bug in Fedora's mingw32-boost package?
