Description Bryce McKinlay 2001-12-22 16:06:00 UTC 
The following test case crashes because no class initialization for "Bar" is generated.

Release:
gcc version 3.1 20011221 (experimental)

How-To-Repeat:
class Bar
{
  static Bar B = new Bar();
  int i = 1;
}

public class Qual2
{
  public static void main(String[] args)
  {
    System.out.println (Bar.B.i);    // crash
    System.out.println ((Bar.B).i);  // crash    
  }
}

Confirmed on 3.3 (20021216), Yes I know that this is an old prelease but still.
But fixed on mainline (20030524).

Hello,

with gcc 3.2.3, 3.3 branch, and mainline (20030524), the testcase here crashes as reported:
Exception in thread "main" java.lang.NullPointerException
   at Qual.main(java.lang.String[]) (Unknown Source)

I cannot reproduce this on the mainline (20030524) on i686-pc-linux-gnu:

This is fixed for 3.4 as noted above by me.
Comment 5 Andrew Pinski 2003-05-28 00:38:48 UTC 
Since this is not a regression I can closing this bug as it is fixed in a later version of gcc.
