SIGBUS on solaris w/ C++ wrapper class.... any ideas???

[Brian Snyder]

Hi all,

I am writing a C++ wrapper class as an interface into certain openSSL
commands, and when I call SSL_write, I get a SIGBUS. I traced through with
gdb and where this call takes place, I tried to 'print ssl' I get:
$5 = (SSL*) 0x656e7449,
then I do 'print *ssl' I get:
Cannot access memory at address 0x656e7449

This is obviously the cause for the SIGBUS as SSL_write(ssl...) tries to
make use of this structure.

Here are my machine stats:

~ 73 >uname -a
SunOS candlestick 5.7 Generic_106541-08 sun4u sparc SUNW,Ultra-5_10
~ 74 >g++ --version
2.95.2
~ 76 >gdb --version
GNU gdb 4.17


Here is my class definition, constructor, and write function... if it will
help, Ill post all my code.  I get no return codes that would alert me to
any problems up until the SIGBUS.

Ive never seen anything like this before, anyone have any advise...

{

  char hostName[80];
  char request[200];
  int port;
  SSL *ssl;
  SSL_CTX *ssl_ctx;
  int sock;

//This can throw a couple different string errors, be prepared!

  { //One time per program execution
    if (prngSeed()==false) //Seed the random number generator!
      throw "PRNG Error";
    //Load all necessary support routines as definied by openSLL
    SSL_load_error_strings();
    SSLeay_add_ssl_algorithms();
    initialized = true;
  }
  strcpy(hostName,HostName);
  ssl_ctx = SSL_CTX_new(SSLv23_client_method());
  ssl = SSL_new(ssl_ctx);
  //openSocket could throw an error, otherwise sets up sock
  openSocket(hostName,port);
  SSL_set_fd(ssl, sock);
  int result = SSL_connect(ssl);
  if (SSL_get_error(ssl,result) != SSL_ERROR_NONE)
  {
    printf ("SSL Connect Errors!\n");
    while (ERR_peek_error()!=0)
      printf("%s\n",ERR_error_string(ERR_get_error(),NULL));
    throw "SSL Error";
  }
}
