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
