[Bug java/26152] New: gtkImage.c complains and crashes the application

[cardona at ucla dot edu]

ImageJ, the public domain scientific-grade image processing application
compiles fine with the gcj-wrapper-4.0 in Kubuntu GNU/Linux-ppc when stripped
of JPEG functionality and its dependance on the tools.jar. But when trying to
open an image, the gtkImage.c file complains:

** ERROR **: file
../../../src/libjava/jni/gtk-peer/gnu_java_awt_peer_gtk_GtkImage.c: line 572
(createRawData): assertion failed: (data_fid != 0)
aborting...


I attach a self-contained test case below. Here are the commands to compile and
run it:

$ /usr/bin/gcj-wrapper-4.0 -g testGtkImage.java
$ /usr/lib/jvm/java-gcj/bin/java testGtkImage


The JFileChooser never shows. Here's the error message:


** ERROR **: file
../../../src/libjava/jni/gtk-peer/gnu_java_awt_peer_gtk_GtkImage.c: line 572
(createRawData): assertion failed: (data_fid != 0)

This is a Debian-specific bug in gcj-4.0. We patch the upstream sources
but the patch we use is somehow broken.

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=335650
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=314704
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=324502

Unfortunately I was not able to fix this bug yet.


Cheers,
Michael

So there is no known patch for this bug then. Are there any plans to tackle the
problem? I understand it cripples lots of applications.

Thanks for looking at the bug report.

In Debian we dont care much about it anymore as soon gcc-4.1 will be
released and the gcj included not have this problem. When its out we
will remove gcj-4.0 from debian unstable and more to gcj-4.1.

Closing as works for me since this bug does not effect the FSF released GCC.

Before the end of this, are there any docs on how to compile the latest stable
GCC, so that I can bypass this bug? The gcc-java webpage is very confusing; I
don't even know if gcc-java can be compiled independently, or I need to compile
the whole GCC, or what!

You can't build just the gcj bits of gcc -- you have to build the whole thing.
There are instructions on the gcc web site:

http://gcc.gnu.org/install/

BTW, thanks for the self-contained bug report.  We like to see reports like
this, since it makes it much simpler for us to see what is going wrong.
