Ah, I see you meant you had the whole corerun VM trying to execute a
trivial example. I'm afraid we're going to need more information to
help. Ideally a small C test-case that has the problem, though it
might be interesting to compare the libcoreclr.so binaries in the -O1
and -O2 cases if you can upload or attach them somewhere.
