Using:
gcj (GCC) 3.4.1 (cygming special)

Building a project called Avrora found here:
<http://compilers.cs.ucla.edu/avrora/release.html>
Version 1.2.0-Beta JAR

With command line:
gcj --main=Main -o avrora.exe avrora-beta-1.2.0.jar

I get an ICE:
Arith.java:276: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

I am not familiar at all with building Java projects, so I'm not sure how to
provide a smaller test case. There looks to be a an Arith.java file in the 
src\avrora\core\isdl\ast
subdirectory of the source code for this project. I don't know how to build just
that module without a bunch of other errors due to my incomplete command-line.
The web page on how to report a bug <http://gcc.gnu.org/bugs.html>, was not very
helpful when it comes to java projects.

Thanks
Eric Weddington

This also fails with current cvs head.

BTW, Eric, you probably want "--main=avrora.Main".
"--main" takes the fully qualified class name,
(just like the "java" command...)

Thanks for the tip! As I mentioned, I don't know anything about building 
Java projects.

------- Additional Comments From tromey at gcc dot gnu dot org  2004-10-01 17:58 -------
I looked into this a little.

The bug is that we never call push_super_field() for the class
in question.  In layout_class, push_super_field can be called,
but we fail this test and skip the call:

  if (super_class && !CLASS_BEING_LAIDOUT (super_class))

In our case, CLASS_BEING_LAIDOUT (super_class) is true.

layout_class is only called once for the class in question,
so we never get another chance to call push_super_field.
Later we die because TYPE_FIELDS is NULL_TREE.

Offhand I'm not sure what to do.
Andrew has been working in this area lately, perhaps he
has an idea.  I will ping him.
