c++ - Boost.Coroutine 在 iPhone 上崩溃

有人尝试在 iOS 应用程序中使用 Boost.Coroutine 库吗？ 如果是，是否有效？

我现在正在尝试这样做，但是当尝试展开堆栈应用程序的不完整协程以未捕获的异常forced_unwind() 终止时。

我已经在其他平台(i386(ios 模拟器)和 elf armv7(htc one x，one v))上运行了这个库，并且运行良好。但是 iOS .. :[

附加信息:

我正在尝试从 boost/coroutine/example 运行 unwind.cpp 示例: https://github.com/olk/boost-coroutine/blob/master/example/cpp03/unwind.cpp

堆栈是:

ARM 上的 IOS 使用不同于 AAPCS(这是标准)的 ABI。 boost.coroutine 在内部使用 boost.context 进行上下文切换/跳转。 直到 boost-1.55，bost.context 不支持 IOS 的 ABI。
