Repro: Run !VerifyHeap in SOS once the runtime starts up (e.g. when entering Main)

Result (on Windows x86):

0:000> !VerifyHeap
Object 08592968 is too large.  End of segment at 085929E4.
Last good object: 085928E4.

The object that VerifyHeap complains about is at the end of the newly introduced frozen heap.
