This crash is in code-zapping, doesn't look related to my change. Ulan, can you triage for GC?

This sounds very similar to  issue v8:7100 , though I don't see --write-protect-code-pages passed to this test.

It is passing --future, which implies --write-protect-code-memory, so pretty sure it's the same.
