Start by examining the failure sequence around src/praft/praft.cc:741 and the PreVote handling logged at Source/extern_braft/src/braft/node.cpp:2321. Use the supplied EXC_BAD_ACCESS logs and screenshot to reproduce the Raft pre-vote scenario; no minimal reproduction, version, or test is provided. Done means the reported pre-vote sequence no longer crashes.
