--- Comment #1 from Yao Qi <qiyao at gcc dot gnu.org> ---
The exception can be either caught in the caller of
the_low_target.prepare_to_resume (lwp) or not thrown out from prepare_to_resume
hook in each backend.

I had a hacky patch for the former approach, and the event loop isn't
terminated by the exception.

-------------------------------------------

However, I still not sure what is the best way to fix this issue.
