Question

So to start off this code works on all my redhat machines and some other solaris machines. The machine that is producing the fault is a solaris 64 bit. The code I have is as follows:

This is the frUUID class:

  frUUID::frUUID()
  {}

  std::string frUUID::genUUID()
  {
    char uuidBuff[36];
    uuid_t uuidGenerated;
    uuid_generate_random(uuidGenerated);
    uuid_unparse(uuidGenerated, uuidBuff);

    std::cout << uuidBuff << std::endl; // prints out a correct uuid

    return std::string(uuidBuff);
  }

Then in a unit test I have:

 frUUID uuids;

 std::string uuid1 = uuids.genUUID();
 std::cout << std::endl << "UUID 1: " << uuid1 << std::endl; 
 //This cout produces the seg fault on the uuid1

I have no idea what is going on here everything seems to be correct? Does anyone have any ideas?

You’re not leaving space for the trailing null byte in uuidBuff.
