Hi Revital,

That sounds like a different problem. I'm going to mark this bug as resolved.

As for the problem you're seeing now: RuntimeDyld::SymbolInfo doesn't do
anything interesting itself, but Symbol.getAddress() may run the
materialization function for that symbol, which could cause all sorts of things
to happen depending on how you set up your JIT stack.

Have you run valgrind or an msan build of your project? This sounds like it
could be a memory error in one of your data structures.

- Lang.
