The good news for anyone that wanted to hack on SGen is that this is a
good place to start.
So Mono runtime with SGen does build, now you have to find every
instance where there is a failure.
Remember that this is not our regular conservative GC, this is a
moving collector, so data in memory will be moved. The challenge is
to find the source of this crash: what caused it? Memory that was
moved? Information that was not pinned and was moved behind the
unmanaged code knowing?
