     Sure, gdb is no problem. This is 32-bit Ubuntu 14.04. It's
reproducible, but uses a fairly elaborate third-party library. Some of
the callbacks are called in a straightforward way, from a VM thread,
others from forked worker threads that the library uses.

     Aha! I hadn't noticed that; cool.

     Hm, now I'm getting "callback failed to invoke"...
