Sorry, I haven't had time to dive into this.

Here are a few more suggestions to help you debug this yourself:
- Run sid with a bunch of tracing options, especially those tracing
  flags that the CPU offers.
- Compile sid with CXXFLAGS="-O0 -g", to make the debug info as simple
  and accurate as possible.
