[Bug java/16178] New: jc1 ICE: seemingly infinite loop while compiling junit

[green at redhat dot com]

I found this regression while building rhug's junit with today's gcj.  I don't
know when the regression first appeared.   It happens while building
TestImplementorTest.java at every -O* level.  No small test case yet.  Here's
the stack trace.

I should have mentioned that the problem is that we're blowing the stack.

I get the same thing with a recent gcj mainline build (3.5.0 20040625) when
trying to compile the Wonka Visual Test Engine. Just try to compile the following:

gcj -c -o com/acunia/wonka/test/awt/IAA/ComboBox.o
com/acunia/wonka/test/awt/IAA/ComboBox.java

(Comes from sources.redhat.com:/cvs/mauve module wonka)

My failure disappeared when removing all .class files from the build directory.
(Even though I was building from .java source files). The .class files were
generated by an older jikes. Regenerating the .class files with jikes 1.21
doesn't trigger the bug. I'll try to see if I can reproduce it using an older jikes.

This PR is eerily similar to PR15768 and PR14439.

Anthony, when you do get this dump, can you do a "debug_tree(0xf6e0b580)"
within GDB - this is the class on which read_class(), etc. are choking. (Or
the parameter to load_class() - either should do.)

If you have some time, you might also want to try out:

  http://gcc.gnu.org/ml/gcc-patches/2004-06/msg01589.html

and see if it helps (I'll be committing it tonight anyway).
