SYMPTOMS
When running Java code with the JIT compiler turned on, some uses of character constants in a loop can cause an Application error to occur. This article describes one example of code that causes an Application error and results in the following error message:

JView.exe - Application Error

The exception Illegal Instruction.

An attempt was made to execute an illegal instruction.

(0xc000001d) occurred in the application at location 0x04041332. Click on OK to terminate the program. Click on CANCEL to debug the program.



CAUSE
This problem is caused by a bug in the way that the JIT compiler handles character constants when unrolling a loop.



STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.

This problem has been fixed in version 3190 and 3236 of the Microsoft virtual machine.

This problem was corrected in Windows 2000 Service Pack 1.



MORE INFORMATION
This code causes the Application error and results in the error message in the "Symptoms" section: public class Test {              private static void DoTest {       for( int i = 0; i < 10; i++ ) {           System.out.println( (char)('a' + i) ); }   }

public static void main( String[] args ) {       System.out.println( "starting" );

DoTest; } }
