Not a bug. You are using TPAR inside the class C1T::S,
however, only C1T is a friend of C2. This is the relevent section
of C++ standard (section 11.4 paragraph 2):
... the declarations of members of classes nested within
the friend class cannot access the names of private and
protected members from the class granting friendship. ...
and the example in the same section:
class A {
class B {};
friend class X;
};
class X : A::B { // ill-formed: A::B cannot be accessed
// in the base-clause for X
A::B mx; // OK: A::B used to declare member of X
class Y : A::B { // OK: A::B used to declare member of X
A::B my; // ill-formed: A::B cannot be accessed
// to declare members of nested class of X
};
};

[Bug target/18034] GCC 3.4.2/GNAT bootstrap problem
--- Additional Comments From franke at euro-telematik dot de 2004-11-27 17:25 --- Subject: Re: GCC 3.4.2/GNAT bootstrap problem -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Try looking into PR 6552 and PR 6669. Those two might tell you what the problem is. It might be stage1 is being miscompile which miscompiles stage2 which causes this problem. I did, but it brought no alleviation. Removing -g from various CFLAGS, as proposed in PR 6669, doesn't change the outcome, while removing -O2 (PR 6552) makes it even worse, as some of the little helper utilities that get built along the way (gentype, genmode, and friends) produce a bus error when executed. Andrew's explanation certainly sounds plausible. Could you try bootstrapping using Rainer Orth's GNAT binaries: ftp://ftp.Uni-Bielefeld.DE/pub/gnu/gnat/binaries/ I've had no problems bootstrapping 3.4 on our IRIX 6.5 when using these binaries as the starting point. Tried that, too. No betterment. And I only have IRIX 6.2 at my disposal. I have, meanwhile, upgraded to GCC 3.4.3, but it didn't make a difference. Out of sheer desparation, I have adopted a brute- force method to get rid of the symptoms (not the problems, though!). See the transcript below. I have finally been able to produce a GCC 3.4.3 but I am all too aware of the fact that it is a botched one. Not surprisingly, it could not be used to bootstrap itself. Any ideas are appreciated.

libcpp no longer uses HOST_WIDE_INT.
The computation which leads to the error is done in c-decl.c in target
arithmetic as follows:
/* Compute the maximum valid index, that is, size
- 1. Do the calculation in index_type, so that
if it is a variable the computations will be
done in the proper mode. */
itype = fold (build2 (MINUS_EXPR, index_type,
convert (index_type, size),
convert (index_type,
size_one_node)));
/* If that overflowed, the array is too big. ???
While a size of INT_MAX+1 technically shouldn't
cause an overflow (because we subtract 1), the
overflow is recorded during the conversion to
index_type, before the subtraction. Handling
this case seems like an unnecessary
complication. */
if (TREE_OVERFLOW (itype))
{
error (size of array %qs is too large, name);
type = error_mark_node;
continue;
}
This looks OK.
Steven, can you possibly check to see whether this bug still exists in
mainline?

/* The name of the object as the assembler will see it (but before any
translations made by ASM_OUTPUT_LABELREF). Often this is the same
as DECL_NAME. It is an IDENTIFIER_NODE. */
#define DECL_ASSEMBLER_NAME(NODE) decl_assembler_name (NODE)
/* Returns nonzero if the DECL_ASSEMBLER_NAME for NODE has been set. If zero,
the NODE might still have a DECL_ASSEMBLER_NAME -- it just hasn't been set
yet. */ #define DECL_ASSEMBLER_NAME_SET_P(NODE) \

Simply calling DECL_ASSEMBLER_NAME will make DECL_ASSEMBLER_NAME_SET_P to

--- Additional Comments From neroden at gcc dot gnu dot org 2004-11-27 23:18 --- Ow. The dependencies are emitted in open_file_failed in libcpp/files.c; but that routine *doesn't know* whether the file was called for in a or a directive. Fixing this requires some restructuring of libcpp code so that the dependencies are emitted in a place which does know (perhaps the same place, but that requires a lot of extra information passing). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15220

[Bug java/18696] New: Miscompilation of GtkMenuItemPeer.setParent(MenuItem)
The setParent(MenuItem) method in gnu/java/awt/peer/gtk/GtkMenuItemPeer.java
gets miscompiled which makes Menu related tests in the Mauve Visual Test Engine
and the AWT demo from GNU Classpath examples crash.
Example (from GNU Classpath 0.12 examples):
gij -cp examples.zip gnu.classpath.examples.awt.Demo
Aborted
A gdb shows the following (impossible!) backtrace:

This has nothing to do with the recent gui-merge patch. It works fine when
compiled with the gui branch compiler and fails in exactly the same why before
and after the gui-branch-merge-patch in the trunk.
It fails in the same way on i686-pc-linux-gnu and powerpc-unknown-linux-gnu
(both configured with --enable-java-awt=gtk,xlib)
gij (GNU libgcj) version 4.0.0 20041127 (experimental)
The following rewrite of the method makes everything work fine.
