crash at SerializedRequest #2961
Description
Describe the bug
SerializedRequest doesn't provide a valid GetClassData method.
To Reproduce
for (brpc::SampledRequest *sample = get_next_sample(); !brpc::IsAskedToQuit() && sample != NULL;
sample = get_next_sample(), ++j) {
brpc::SerializedRequest req;
req.serialized_data() = sample->request.movable();
chan->CallMethod(NULL /*use rpc_dump_context in cntl instead*/, cntl, &req,
NULL /*ignore response*/, NULL);
}
Expected behavior
Versions
OS: ubuntu20.04
Compiler: clang-14
brpc: 1.12.1
protobuf: 27.3
