[jhc] [BUG] A pointer used by program is sweeped by GC

[Kiwamu Okabe]

Hi, jhc hackers.

A team member, mzp, found following error while developing Ajhc.

A pointer used by program is sweeped by GC · Issue #51 · ajhc/ajhc
https://github.com/ajhc/ajhc/issues/51

I think the error occurs also on jhc.
But I do not understand jgc's GC root policy, then can't fix it.

Someone has any idea to fix it?

Best regards,
