I just change line 233 to
char buf ; buf = reinterpret_cast<char>(string_buf);
Now the memory usage do not continuously increase and valgrind report has no more definitely lost
in uuid.cpp line 233
...
void zmq::uuid_t::create_blob ()
{
char buf = new char; buf = reinterpret_cast<char>(string_buf);
#ifdef UNICODE // we need to jump twice as far.
blob_buf [0] = convert_byte (buf + 0);
...
when rapidly connect and disconnect to bind socket, the memory usage continuous increase
valgrind report:
==18534== 39,894 bytes in 39,894 blocks are definitely lost in loss record 82 of 86
