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:
#0 0x0eee3144 in Java_gnu_java_awt_peer_gtk_GtkMenuPeer_delItem (env=Variable
"env" is not available.

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.

I can't do anything with this bug because there's no instructions for
reproducing it.
Please provide a step-by-step way to demonstrate the bug.

Added the Menu part from GNU Classpath examples as simple testcase.
Unfortunately after updating gcc again (version 4.0.0 20041128 (experimental)) I
hit [Bug java/18699] SIGSEGV in GC_local_gcj_malloc with this on i686-pc-linux-gnu.
