 Hi Dara,
 
 Note that I was able to reproduce this problem on my particular  
 LinuxPPC machine only. I do not have access to such a machine right  
 now, so I cannot event try to reproduce it. I know that mark@klomp.org  
 also investigated this problem but was unable to reproduce it.
 
 So go ahead and close it.
 
 Regards, Otto

 Hello,
 
 this bug was last update over a year ago. Is it still a problem? With  
 gcc 3.2, 3.3 branch and mainline (20030511) on i686-linux, the problem  
 does not appear. Thanks,

 Hi,
 
 I get the following resuts, which are not very useable, I think. If the 
 problem is only reproducable on my machine, maybe we should leave the 
 matter, so you can spend more time on things that are useful for more 
 people. There is a simple workaround, so I am not really bothered by 
 this.
 
 \Gr, Otto

 Hi,
 
 I tried on both x86 and powerpc on Debian GNU/Linux (testing/woody) with
 gcj 3.0.2 and glibc 2.2.4 but couldn't reproduce it anymore.
 
 Cheers,
 
 Mark

 Hi,
 
 I tried to reproduce the problem with my current setup (same (gcc 
 version 3.0.2 20011014 (prerelease)) version of gcc/gcj/gij, but minor 
 updates of some other packages). Now gij doesn't dump core, but just 
 hangs, with a zombie child process:
 
 [otto@power otto]$ ps axuw | grep gij
 otto      5951  0.8  3.0  9472 7904 pts/0    S    07:55   0:00 gij 
 HelloWorld
 otto      5952  0.0  0.0     0    0 pts/0    Z    07:55   0:00 [gij 
 <defunct>]
 [otto@power otto]$
 
 
 I do not know which lib causes this different behavior. I do remember 
 though, that the core dump was of no use, since gdb on LinuxPPC doesn't 
 work with gcj/gij very well. It justs says seg fault, with no stack 
 backtrace.
