        ICE reported:
          gcj -femit-class-files -Isource -foutput-class-dir=bin ...
./source/gnu/xml/dom/JAXPFactory.java: In class `':
./source/gnu/xml/dom/JAXPFactory.java: In method `(org.xml.sax.XMLReader,gnu.xml.dom.JAXPFactory)':
./source/gnu/xml/dom/JAXPFactory.java:162: Internal compiler error in generate_bytecode_conditional, at java/jcf-write.c:1350
Please submit a full bug report,
with preprocessed source if appropriate.
        This particular line of code is the "if":
            // if validating, default to treating validity errors as fatal
            if (factory.isValidating ())
                producer.setErrorHandler (this);
        This is a static final inner class.
        "factory" an instance of the enclosing (public final) class.
        "isValidating" is inherited from its (abstract) superclass.

Notice:  (a) ICE, (b) bogus diagnostic for classname

The ICE is essentially for an assertion
that state->code_SP didn't change (presumably,
while compiling that "if").
>How-To-Repeat:
        Get a current copy, from CVS, of the GNU JAXP project.
        That's CVS from http://savannah.gnu.org/software/classpathx,
        the "jaxp" module. (The file in question is version
        1.3 in my version, dated 2001/6/24)

        Configure; change the JAVAC line in Makefile to 
JAVAC = gcj -femit-class-files -Isource -foutput-class-dir=$(CC-DESTDIR)
        Make.  See the ICE.
>Fix:
none known.  It may be that more current
versions of GCJ don't have this ICE.
