      Description

      Hi!

      I got a crash while dropping index:

      #include <assert.h>
      #include <stdio.h>
      #include <stdlib.h>
      #include <string.h>
       
      #include <wiredtiger.h>
       
      #define WT_HOME "drop_index.db"
       
      #define WT_CALL(call) \
          do { \
              const int __rc = call; \
              if (__rc != 0) { \
                  fprintf(stderr, # call " at (%s:%d) failed: %s [%d]\n", __FILE__, __LINE__, wiredtiger_strerror(__rc), __rc); \
                  exit(EXIT_FAILURE); \
              } \
          } while (0)
       
      int
      main(void)
      {
          WT_CONNECTION *conn;
          WT_SESSION *session;
       
          assert(system("rm -rf \"" WT_HOME "\" && mkdir \"" WT_HOME "\"") == 0);
       
          WT_CALL(wiredtiger_open(WT_HOME, NULL, "create", &conn));
          WT_CALL(conn->open_session(conn, NULL, NULL, &session));
       
          WT_CALL(session->create(session, "table:main", "columns=(k,v)"));
          WT_CALL(session->create(session, "index:main:index", "columns=(v)"));
       
          WT_CALL(conn->close(conn, NULL));
       
          /* Re-open and try to drop index */
          WT_CALL(wiredtiger_open(WT_HOME, NULL, NULL, &conn));
          WT_CALL(conn->open_session(conn, NULL, NULL, &session));
       
          WT_CALL(session->drop(session, "index:main:index", NULL));
       
          WT_CALL(conn->close(conn, NULL));
       
          return 0;
      }
      

      GDB session

      Looks like

      ()

      function called from

      ()

      doesn't set

       

      pointer when index isn't opened yet.
