Hi,
with Rakudo version 2016.10-37-g127b3be built on MoarVM version
2016.10-15-g715e39 (and --debug=3 on the MoarVM) I get a segfault with
the backtrace at the end.

This is with the tests of https://github.com/jonathanstowe/Squirrel and
I am currently not able to replicate with a smaller example as it seems
to do it after an unpredictable number of tests though I will continue
to try as I'd like to get this working again (this is only fairly
recent.)

Hi,
with Rakudo version 2016.10-37-g127b3be built on MoarVM version
2016.10-15-g715e39 (and --debug=3 on the MoarVM) I get a segfault with
the backtrace at the end.

This is with the tests of https://github.com/jonathanstowe/Squirrel and
I am currently not able to replicate with a smaller example as it seems
to do it after an unpredictable number of tests though I will continue
to try as I'd like to get this working again (this is only fairly
recent.)
