Boost.Coroutine在iPhone上崩溃

Question

Is someone trying to use Boost.Coroutine library in iOS applications? If yes, is it have worked?

I'm now trying to do that, but when incomplete coroutine trying to unwind stack application is terminating with uncaughing exception forced_unwind().

I have run this library on other platform (i386 (ios simulator) and elf armv7 (htc one x, one v)), and it worked fine. But iOS.. :[

Additional information:

I'm trying to run unwind.cpp example, from boost/coroutine/example: https://github.com/olk/boost-coroutine/blob/master/example/cpp03/unwind.cpp

Stack is:

libc++abi.dylib: terminating with uncaught exception of type yboost::coroutines::detail::forced_unwind

Answer 1

IOS on ARM uses a different ABI than AAPCS (which is the standard). boost.coroutine uses internally boost.context for context switching/jumping. Until boost-1.55 bost.context does not support IOS's ABI.
