These following have been verified and will be fixed in an upcoming release.

Multiple Declarations (FIXED)

• multiple declarations in single statement causes crashes/undefined behavior. Example:

   // bug: this causes bad things to happen
   int a, b;

Here is a workaround until the bug is fixed:

   // workaround
   int a; int b;

Sporking Non-static Member Functions (FIXED)

• spork a non-static member function causes crashes/undefined behavior. Example:

   class X
   {
       fun void foo() { <<< "hi" >>>; }
   }
   
   X x;
   
   // bug: causes crash and undefined behavior
   spork ~ x.foo();

Here is workaround, using a wrapper:

++/-- inline bugs (FIXED)

• ++/-- causes incorrect behavior when used inline. Example:

   // bug
   i++ * y++ => z;

Workaround: split into multiple statements

Static class variable initialization

• static class variables are initialized incorrectly. Example:

   class X
   {
       // bug - this is not initialized
       static Object our_object;
   }

Here is a workaround:

   class X
   {
       // declare as reference
       static Object @ our_object;
   }
   
   // initialize outside class
   new Object @=> X.our_object;

Extending Non-public classes to Public classes (FIXED)

• this doesn't work:

   class myEvent extends Event
   {
       int value;
   }

   public class bla
   {
       myEvent some_event;
   }

Log/output not flushed on Windows XP

• output are not flushed correctly on XP.
