Hello everyone,
I'm running a GNU Radio program in standalone C++ application. I experience
something strange with the Socket PDU block.
In a header file, the Socket PDU object is declared as follows:
gr::blocks::socket_pdu::sptr m_TCPServer;
and in the implementation file, the object is initialized like this:
m_TCPServer = gr::blocks::socket_pdu::make("TCP_SERVER","127.0.0.1","2001");
Tracing the debugger output, the SIGSEGV signal is triggered by the
reactive_socket_service_base::destroy(...) function. In particular,
the debugger points to the
reactor_.deregistor_descriptor(..) function.
All help is warmly welcomed.
DISCLAIMER: The program is run on a machine with an old version of GNU
Radio (3.7.11.1), which can't be updated (for security reasons).
Regards,
Moses.
void reactive_socket_service_base::destroy(
reactive_socket_service_base::base_implementation_type& impl)
{
if (impl.socket_ != invalid_socket)
{
BOOST_ASIO_HANDLER_OPERATION(("socket", &impl, "close"));
reactor_.deregister_descriptor(impl.socket_,
impl.reactor_data_,=====> Debugger points to this line
(impl.state_ & socket_ops::possible_dup) == 0);
boost::system::error_code ignored_ec;
socket_ops::close(impl.socket_, impl.state_, true, ignored_ec);
}
}
