Hi,
I ve a c++ code that interconect different classes with zeromq. I work in
Ubuntu 12.04 and the Zeromq version is 3.2.1
A module sends google protobuf in the 0mq socket and other module receives
it and save in a database. When the code runs for 10 seconds or less I can
show this error:
Assertion failed: ok (mailbox.cpp:84)
the dmesg said:
[13436.436619] TWISTTestbedCAg[9592]: segfault at 0 ip (null) sp b2efefac
error 14 in TWISTTestbedCAgent[8048000+17000]
and the gdb core:
El programa terminó con la señal 11, Segmentation fault.
#0 0xb768f182 in
google::protobuf::MessageLite::ParseFromString(std::string const&) () from
/usr/lib/libprotobuf.so.7
(gdb) bt

The piece of code with that fuction is:
//Receive ZMQ message and convert into protobuf object
bool VirtualControlChannel::RecvProtoBuf(::google::protobuf::Message
&protobuf)
{
int flag;
assert (this->sock != NULL);
zmq::message_t message;
flag = this->sock->recv(&message);
if (flag == -1)
{
throw std::runtime_error("Failed to receive zeromq message: ");
}
std::string buffer(static_cast<char*>(message.data()), message.size());
printf("Message size: %d\n", message.size());
std::cout << std::flush;
if (!protobuf.ParseFromString(buffer))
throw std::runtime_error("Failed to parse protobuf message");
return true;
};
Do you know form where the problem comes?
Best regards,
