I'm seeing this as well, and not only on Linux/x86_64.

It's not a "classical" GC-safety bug: the DEBUG_GCSAFETY build does not
flag any violation of the GC-safety rules.

We will need additional tooling in order to track down this one.
I have some ideas (valdgrind, gcc -fsanitize, and others).
If you have other ideas how to isolate this kind of bug, please speak up!
