SIGSEV coredump #1732

Hi.

I made a script to read rss in the terminal. This script uses the following libraries:

DBIish; DateTime::Parse; Cro::HTTP::Client; XML; Term::ReadKey; Term::termios; HTML::Entity::Fast;

This script will explode with a SIGSEGV and create a coredump. However when i use MVM_SPESH_DISABLE=1 the script doesn't explode.

The code contains:

    react {
        whenever Supply.interval(120) {

            start {
                log("Start thread!");
                $lock.protect: {
                    # Uses Cro::HTTP::Client to download the RSS
                }
            }
        }

        whenever Supply.interval(30) {
...
}
