Re: [Boost-users] [coroutine] - only std exceptions are caught from coroutines

Hi,

I use boost coroutines and I have realized that in my environment (Visual Studio 2015 Update 1, x64) I cannot catch the exception type of a custom exception.

The example below demonstrates the case. I have a custom exception derived from a std::runime_error. In the main function I want to catch my custom exception type that was thrown in the coroutine. However somehow I always end up in the catch branch of the std::runtime_error.

Are custom exceptions are not supported by the coroutines library?

boost.coroutine - no (->boost.exception's exception_ptr) but if you use boost.coroutine2 (C++11), the exception will be catched by 'catch (MyException const&)' clause
