    Details

      Description

      This problem is similar to MDEV-15834, but for a 10.2 specific code in the code branch for MYSQL57_GENERATED_FIELD:

      vcol_info_length= uint2korr(vcol_screen_pos + 1);
      ...
      DBUG_ASSERT(vcol_info_length);
      ...
      vcol_screen_pos+= vcol_info_length + MYSQL57_GCOL_HEADER_SIZE;
      

      In case of a broke FRM file, this can crash in the debug build or behave unpredictably in a release build.
