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.) #0 0x00007ffff7911487 in gc_mark (tc=0x6037d0, st=<optimized out>, data=<optimized out>, worklist=0x6511d40) at
