[ruby-core:89941] [Ruby trunk Bug#15329] Native implementation of coroutines - segfault

[samuel@oriontransfer.net]

Issue #15329 has been updated by ioquatix (Samuel Williams).


Native fiber implementation is all about speed and consistent interface across all supported platforms. It's good to hear there is speed improvement on WSL with native fiber. It also looks like it's a little bit faster than CreateFiber Win32 API.

> commits after that including the lastest trunk and your native-fiber branch always fails. What's rvm doing differently?

Can you show me the report of failure?
