[Mono] Fix uninitialized vtable bug (#67746)

simonrozsival · web-flow · commit e74da7c72c81 · 2022-04-12T16:25:47.000-04:00
Fixes #67402 The code which checks whether a class derived from System.IO.Stream has overridden certain methods didn't explicitly setup the vtable before it tried to dereference the vtable pointer. When AOT was enabled the vtable pointer was null and dereferencing it caused a crash.
