      Description



      Name: akC45999 Date: 05/18/98



      The following test fails on JDK 1.2beta4F with diagnose:

      Segmentation Fault (core dumped)

      if JIT is enabled. If it is off, test passes.

      ------------------------------ file recur.java
      public class Recur {
         volatile int count=0;

         synchronized double recur(double arg) {
      count++;
      // hack to avoid optimization of tail recursion
      if (arg>0) return recur(Math.sin(arg))+arg;
      else return recur(Math.cos(arg))*arg;
        }

        public static void main(String args[]) {
      Recur rec=new Recur();
      try{
      rec.recur(1.0);
      System.exit(rec.count);
      } catch (StackOverflowError e) {
      System.out.println("count="+rec.count);
      }
        }

      }

      ------------------------------ end of file recur.java
