Hi,

There is a recent update which broke my Java IDE (Eclipse - not from
portage) .

I've seen this strange behavior in 2 different machines, both ADM64, but I'm
not sure which package should I inform to this error:

Perhaps you should rebuild Eclipse so it can link against your new libraries.

What I have tried so far:

-reinstall sun-jdk
-run revdep-rebuild
-download older/newer Eclipse version

I've submitted a new bug anyway:

Why don't you try icedtea instead of sun-jdk?

Two notes, here:

1) I don't know about sunjdk as there's license issues such that I won't
install it, but the iced-tea6-bin package, while free, is a pre-compiled
binary install. As such, revdep-rebuild won't be able to do anything for
it as it'll just reinstall the same binary, so the package installs a
revdep-rebuild control file so revdep-rebuild skips checking it, to
prevent reinstalls that wouldn't fix anything.

FWIW there's the icedtea package for from-source building, but the build-
process is said to be quite convoluted, many dependencies, etc., thus the
binary package option.

If the sunjdk package similarly has binary components, since that's what
originally triggered the bug, that /might/ be your issue. However, I
don't know that it does.

2) What version of glibc do you have? Unless you're running ~arch or even
masked/live, this probably doesn't apply, but... LWN article posted Nov
10, 2010 about a glibc change to memcpy behavior when used in a context
with specifically undefined behavior:

http://lwn.net/Articles/414467/

Also see the Nov 24, 2010 longer LWN commentary article, which covers both
the glibc change and a kernel behavior change, examining how they were
handled when found to break things, etc.

http://lwn.net/Articles/416821/

FWIW, I'm with the glibc folks here. The behavior is specifically said to
be undefined when the memory regions overlap, and think about it, if your
memory source and destination regions overlap, by definition it's not a
simple copy anyway, as the data in the source region has changed at the
end and with a simple copy, it should intuitively be the same as it was --
unless you overlap the copies, but then that's not a simple copy so
shouldn't be using the copy function! Duh!

The kernel thing is specifically different, in part because Linus has
established clear rules about breaking the kernel/userspace interface (in
a word, don't!) -- part of the reason that change was reverted. If it had
instead been specifically documented as changeable, much like the kernel's
internal interfaces are (much to the dismay of many closed-source kernel
module devs)... the outcome there would likely have been similar to the
glibc outcome.

It was actually quite easy now to emerge icedtea from source, you just need
to add the java overlay and then emerge as usual. After emerge and if you
are keeping the binary icedtea or sun's, you'd then need to point your
preferred java vm using eselect.

(Apology for the top post, the Gmail client in Android 2.1 doesn't allow you
to even delete the quoted text, this was fixed in 2.2 but you and I had to
bear with this for the moment)

You don't even have to add the overlay any more. Icedtea 6 is in the
main tree as dev-java/icedtea.

Anyway, I have tried with:

sun-jdk-1.6.0.23
icedtea-6.1.9.4
icedtea6-bin-1.9.4

And I always get the same error:

*** glibc detected *** java: free(): invalid pointer:

Today I noticied if I run using root Eclipse doesn't crash.

glibc is reporting to you about the error, FYI you can control its
behavior (ignore, warn, abort) with the MALLOC_CHECK_ variable. See
"man malloc" and scroll to the last paragraph. Maybe running as root
operated under a different malloc mode?

Looks like maybe your file
/home/fb/eclipseWTP3.2.3/configuration/org.eclipse.osgi/bundles/151/1/.cp/libswt-pi-gtk-3657.so
is the common thread...

I think the only way to really know exactly where it's crashing is to
build everything involved with debug symbols and debug the coredump or
use valgrind or something like that. If Eclipse is a binary install
then I guess report it to whoever makes it (I don't know anything
about Java or Eclipse).

Are you compelled to use an unstable version of glibc? Maybe drop back
to 2.11.2-r3? Maybe look at the diffs between 2.11.2 and 2.12.2
relating to memory, and file bugs with the guilty parties?

Given that in another email he mentioned that running eclipse as root
doesn't crash, then it's more likely that the problem is due to the
updating of various eclipse files in the user workspace.

To confirm, just try starting eclipse with a different workspace, using
the following (untested)
$ eclipse -data /home/fb/eclipse_test_workspace

Also compare
/home/fb/eclipseWTP3.2.3/configuration/org.eclipse.osgi/bundles/151/1/.cp/libswt-pi-gtk-3657.so
against
/usr/lib64/eclipse/configuration/org.eclipse.osgi/bundles/151/1/.cp/libswt-pi-gtk-3657.so
and see if the corresponding one on the system both exists and is the
same. (particularly since this appears to be your problem file)

I suspect not. I thought that updating of various core
libraries/bundles of eclipse was disabled on most linux distros due to
eclipse being built against the system version of glibc, but a update
there is the only way I can think that it could go from working to
crashing after an eclipse update.

Paul, maybe you are right about root behavior, but I'm not an expert =)

Darragh, I don't have this directory: /usr/lib64/eclipse/
