Segmentation violation during compilation

    Details

      Description



      Name: ngC57085 Date: 05/19/98



      The test lang/CONV/conv047/conv04703 is not compiled by jdk1.2beta4F with JIT
      under win32. Segmentation violation occurs.

      Unfortunately this bug is unstable. To resieve segmentation violation
      test compilation may be repeated sevaral times.
