std::bad_alloc运行时异常

当for循环到达第二轮时，我在服务器端收到 std：：bad_aloc 异常。这是代码：

void UDP_ProcessClient (int socketFileDescriptor, void *transmitBuffer, void *receiveBuffer, size_t transmitBufferSize, struct sockaddr *clientAddress, socklen_t clientAddressLength, char *workDir, size_t fileNumber)
{
size_t i;
size_t bufferSize = 0;
string resultName, imageName;
for (i = 0; i < 6; i++)
{
/// Start communicating (read/write)
/// Prepare buffers for communication
cout << "[Server]: Receiving data from client..." << endl;
UDP_ReceiveData(socketFileDescriptor, (uint32_t *) &bufferSize, sizeof(bufferSize), MSG_WAITALL, clientAddress, &clientAddressLength);      /// Get required data buffer size
//cout << "[Server]: PHPDHPHPHFPSADHFI" << endl;
receiveBuffer = new uint8_t[bufferSize];                                                                                                    /// Allocate memory
clog << "Receiving file of size " << bufferSize << endl;
UDP_ReceiveData(socketFileDescriptor, (int8_t *) receiveBuffer, bufferSize, MSG_WAITALL, clientAddress, &clientAddressLength);              /// Read data
//cout << "SDFDSFDSFFADSFASDFSDVLALALL " << bufferSize << endl;
cout << 'a';
cout << "[Server]: Data received successful" << endl;
/// Save image.bmp file
resultName = workDir;
imageName = "image_" + to_string(fileNumber) + ".jai";
resultName += imageName;
createImageFromBuffer((uint8_t *) receiveBuffer, bufferSize, resultName);
/// Clear memory
bufferSize = 0;
delete[] (uint8_t *) receiveBuffer;
}
}

在每次分配内存后，new []在回合开始时，我不会忘记在每轮结束时释放delete []它。 收到的所有文件大小相同。我可以显示客户端代码，但我认为它工作正常。

客户端代码：

for (i = 0; i < 6; i++)
{
/// Do useful work (payload)
/// Prepare files
imageFileFullName = pathToImageFiles + imageFileName + std::to_string(i) + imageFileFormat;
std::clog << "Opening file..." << std::endl;
imageFile = new std::fstream;
imageFile->open(imageFileFullName, std::ios::in | std::ios::binary | std::ios::ate);
//checkFileOpened(imageFile);
if (!(imageFile->is_open()))
{
std::cerr << "Can't open file " << imageFileFullName << ": ";
perror("");
exit(EXIT_FAILURE);
}
imageFileSize = imageFile->tellg();
imageFile->seekg(0, std::ios::beg);
/// Prepare transmit buffer
transmitBuffer = new uint8_t[imageFileSize];
std::cout << "Reading file..." << std::endl;
imageFile->read((char *) transmitBuffer, imageFileSize);
imageFile->close();
delete imageFile;                                           /// Delete used file
/// Send/Receive Data to/from Server
std::cout << "Sending file..." << std::endl;
UDP_SendData(socketFileDescriptor, &imageFileSize, sizeof(imageFileSize), MSG_CONFIRM, (struct sockaddr *) addressIterator_Pointer->ai_addr, addressIterator_Pointer->ai_addrlen);
UDP_SendBigPacket(socketFileDescriptor, (uint8_t *) transmitBuffer, imageFileSize, MSG_CONFIRM, (struct sockaddr *) addressIterator_Pointer->ai_addr, addressIterator_Pointer->ai_addrlen);
delete[] transmitBuffer;                                    /// Free memory
}
...
