[Bug java/16181] New: dequeue_and_dump: accessed operand 1 of this with 0 operands

[cconway at lucent dot com]

I'm seeing the following error when I try to dump the parse tree from a java
program (the syntax errors are irrelevant and can be ignored):

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

I can't figure out how to attach a .java file, so I'll commit this bug and try
to attach it post facto.

I think you need a new prelease as I cannot reproduce it on <gcc version 3.5.0 20040624 
(experimental)>.

GCJ does not support tree dumping for a source file that has syntax errors.

Valid syntax required to dump trees.

The syntax errors are an artifact of pulling the source file out of its project
context. The same error occurs when the class is compiled alongside other
project files and there are no syntax errors. If you need to see the class in
situ to verify the bug, I will have to attach a significant chunk of source
code. (The whole project is open source and freely available:
http://sdg.lcs.mit.edu/TSAFE/downloads/) 

What can I do to provide you with the information you need? "-save-temps"
doesn't seem to work.

Try a new compiler it works for me.
