Getting Corrupted Size Segmentation faults during run

[Deepankar Agrawal]

Hi Everyone,

I am running a grpc client, which is sending a lot of requests with the audio payload. Most of the requests work fine but sometimes the client crashes with the below error.

#1 0x00007f1a8742a03a in __GI_abort () at abort.c:89
#2 0x00007f1a8746a7fa in __libc_message (do_abort=2, fmt=fmt @entry=0x7f1a87583f98 "*** Error in `%s': %s: 0x%s ***\n") at ../sysdeps/posix/libc_fatal.c:175

I am using c++ async streaming client. I have two functions, in one i get payload that needs to be sent to the server. This function needs to be async. Another is my grpc thread, in which I am writing to grpc channel writer. My code crashes there when I am resetting the payload length to 0.

My code is something as follows:

private:

   cca::TaskRequest task_request;

// just adds payload to grpc object TaskRequest

void ProcessStreaming(void* audio_bytes, int length) {

  task_request.set_payload(audio_bytes, length);

}

void GrpcThread() {

   if (task_request.payload().length() != 0) {

     writer->Write(task_request, reinterpret_cast<void*>(Type::WRITE));

     task_request.set_payload("", 0); // crashes here

}

Here is proto definition of TaskRequest. There are more fields but I have just added the minimum info required.

message TaskRequest {

  bytes payload = 1;

}

Thanks in advance for any help in understanding this error.
