I'm hoping I can get the GC's memstomp/sentinel to find it, although that 
might not work if it's a bug in the GC itself.

My other option is fixing my execution trace debugger (seems to get lost 
inside a system dll) and spend a few days tracing backwards from the 
segfault.

At least I found the (an) optimizer bug:
