[Bug java/31719] New: gcj crashes compiling simple .class file output by Rhino js->.class compiler

[billt at tutsys dot com]

I'm trying to compile a .class file generated from the following Javascript
program using Rhino 1_6R5 (Mozilla's Javascript compiler):

  print("Hello, world");

When I do so from within Rhino's src/ directory (so that gcj can find the Rhino
java files to satisfy dependencies), I get a simple error:

  jc1: internal compiler error: Segmentation fault
  Please submit a full bug report,...

"uname -a" says:
  Linux cpxa03b 2.4.25-rm02.mcp820 #17 Wed Sep 14 09:20:59 PDT 2005 ppc unknown

I can attach a .class file if that would be useful.

Sorry about that.  I forwarded it to our bugzilla maintainer.

Can you email me the class file instead?
Thanks.

Dan Berlin said if you log in first you should be able to attach things.

I downloaded rhino 1_6r5 from: http://www.mozilla.org/rhino/download.html
Then I tried the .class you sent me.  I tried with gcj 4.1 (from the 4.1
branch), the FC6 gcj, and svn trunk.  All worked.  I did this:

gcj -c -I rhino1_6R5/js.jar lame.class


I did get an ICE when running from rhino1_6R5/src:

opsy. gcj -c ../../lame.class 
./org/mozilla/javascript/Context.java:565: warning: The class
‘org.mozilla.javascript.ContextListener’ has been deprecated.
    public static void addContextListener(ContextListener listener)
                                             ^
./org/mozilla/javascript/Context.java:594: warning: The class
‘org.mozilla.javascript.ContextListener’ has been deprecated.
    public static void removeContextListener(ContextListener listener)
                                                ^
jc1: internal compiler error: Segmentation fault

... but it is really better to use the -I method from the first example,
especially since trunk can't readily compile class files whose dependencies
only exist as .java files.

ICEing here is still bad of course.  We should emit a sensible error and
exit cleanly instead.
