      Description



      Name: laC46010 Date: 07/28/98


         All VM version (1.0-1.2FCS-C) crash on all platforms while
      execute classfile with constant pool with a big quantity of literals.
      Segmentation violation occurs if a classfile contains from 16384 to
      32768 double literals or from 32768 to 65536 float literals. It is
      reproduced with or without jit.
         The same happens when 10922 and more methods declared in one
      classfile.

      The program which generates an example and VM diagnostics follow:
      -----------------------------------------------------------------
      cat test1.java
      class test1 {

         static int ARRAY_N = 4; /* Array number */
         static int CPA = 4096; /* Constants per array, use 8192 for float */
         static int CPL = 10; /* Constants per line */
         static String TYPE = "double";/* Array type, use "float" for float */
         static String TS = ".0"; /* Constants suffix, use "f" for float */

          public static void main(String[] argv) {
            int TOTAL = 0;
            System.out.print("import java.io.PrintStream;\n\n");
            System.out.print( "class test {\n\n");
            for (int i = 0; i < ARRAY_N; ++i) {
               int COUNT = 0;
               System.out.print(" static "+TYPE+"[] arr"+i+";\n");
               System.out.print(" static void m"+i+"() {\n");
               System.out.print(" arr"+i+" = new "+TYPE+"[] {\n");
               for (int l = 0; l <= CPA/CPL; l++) {
                  String const_line = " ";
                  for (int j = 0; (j < CPL) && (COUNT++ < CPA); j++)
                    const_line = const_line + (j==0 && l==0 ? "":",") + TOTAL++ + TS;
                  System.out.println(const_line);
               }
               System.out.print(" };\n }\n");
            }
            System.out.println(" public static void main(String args[]) { System.out.println(\"Ok\"); }");
            System.out.println("}");
         }
      }
