I get a seg fault in ssl_engine_vars.c line 658.

Here is part of the gdb back trace:

(gdb) run -X

The fix is simple in ssl_engine_vars.c:

  static const char *ssl_var_log_handler_c(request_rec *r, char *a)
  {
      SSLConnRec *sslconn = myConnConfig(r->connection);
      char *result;

+     if (sslconn == NULL) // check for bad return
+        return NULL;      // 
      if (sslconn->ssl == NULL)
         return NULL;
