Description Andrew Overholt 2005-02-22 17:13:05 UTC 
Description of problem:
Just as with gcc head, gij fails as in:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19823

Version-Release number of selected component (if applicable):
gcc-java-3.4.3-19

How reproducible:
Always

Steps to Reproduce:
1. Input HelloWorld like so:
public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, world.");
    }
}
2. gcj -C HelloWorld.java
3. gij HelloWorld
  
Actual results:
Exception in thread "main" java.lang.NullPointerException
   at gnu.gcj.runtime.FirstThread.call_main() (/usr/lib/libgcj.so.5.0.0)
   at gnu.gcj.runtime.FirstThread.run() (/usr/lib/libgcj.so.5.0.0)
   at _Jv_ThreadRun(java.lang.Thread) (/usr/lib/libgcj.so.5.0.0)
   at _Jv_RunMain(java.lang.Class, byte const, int, byte const,
boolean) (/usr/lib/libgcj.so.5.0.0)
   at __libc_start_main (/lib/tls/libc-2.3.4.so)

Expected results:
Hello, world.

Additional info:
I believe Bryce McKinlay is working on back-porting the gcc head fix
to the gcc34 branch.
Comment 1 Jakub Jelinek 2005-02-22 17:14:43 UTC 
I have it backported, just haven't built the packages yet.
Comment 2 Andrew Overholt 2005-02-22 17:21:07 UTC 
Cool.  I'd like to build a new version of gjdoc (an actual released non-beta
version this time) and that depends upon this.  It's not a huge deal, though.

BTW, will you apply your backported fix to upstream as well?
Comment 3 Bryce McKinlay 2005-02-23 01:06:19 UTC 
FYI I have checked in the patch to the upstream gcc 3.4-branch
Comment 4 Jakub Jelinek 2005-02-23 14:42:42 UTC 
Should be fixed in gcc-3.4.3-20.
