> Hi, please consider the following changes:
>
> The problem in the issue description is not a problem by itself, the behavior is not unexpected, but it is somewhat difficult to find out what caused SIGILL to be fired.
>
> We propagate this information from `handshake::handle_timeout()` to `VMError::report()` with a help of a global variable. The same mechanism is used to address a similar issue in the safepoint timeout handler.
>
> Tested in tiers 1-3.
