Description

Current code static_casts the provided Context to C_AioRead when the actual type is ObjectCacher::C_ReadFinish. Therefore read op flags are always incorrectly set and a crash will occur whenever the Context is near the end of the heap.

124          AioRead *req = (static_cast<C_AioRead *>(onfinish))->get_req();

(gdb) set print object on
(gdb) ptype onfinish
type = /* real type = ObjectCacher::C_ReadFinish * */
