The same thing works perfectly if javac (==ecj) was compiled with gcj 4.1.1
instead of 4.2.0.

Created an attachment (id=12085)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=12085&action=view)
Simple test case
Attaching a simple test case -- in the "test" directory contained in this
tarball,
make works
produces the expected result
make breaks
causes a (wrong) NullPointerException.
The difference between the make targets is that "make works" uses gij, "make
breaks" binary-compiles with gcj.

I bet this is the same problem as PR 28663.
Also there is no makefile in the tarball so there is no way to test anything
here.

I tried to look at this today but the test is missing
a main method (I could work around the lack of a Makefile,
but this is more serious...)

Real test case
Oops, must have attached the wrong file, that was the test case for a much
older problem (PR24598, which turned out to be compiler flag related)
Attaching the real test case that was meant for 28754. I haven't checked yet if
it still breaks in current SVN though

------- Comment #6 from tromey at gcc dot gnu dot org 2006-09-11 23:26 -------
Thanks for the updated test.
It fails for me if I compile it to .class with ecj, but not
if I compile it to .class with gcj.
The difference is in the qualification of the reference to
SUFFIX_CLASS in test2 .. ecj generates
3: getstatic #24=<Field test2.SUFFIX_CLASS char[]>
but gcj uses test1 as the qualifier.
ecj is correct here fwiw.
I think the in C++ ABI case we probably should simply initialize
the interface that declares the field.
