[gentoo-user] *** glibc detected *** double free or corruption (!prev): 0x08067d98 ***

[Stroller]

I'm sure I've had this before, but I'm knackered if I can remember  
how I fixed it.

Leafnode was working perfectly fine until a few days ago, then all of  
a sudden when I try to grab messages from upstream I get the following:

    $ sudo fetchnews -vvv
    Password:
    fetchnews mode: get articles, get headers, get bodies, post articles
    erased stale pid 1097 host quattro.stroller.uk.eu.org lockfile / 
var/spool/news/leaf.node/lock.file
    *** glibc detected *** double free or corruption (!prev):  
0x08067d98 ***
    Aborted
    $ sudo rm /var/spool/news/leaf.node/lock.file
    $ sudo fetchnews -vvv
    Password:
    fetchnews mode: get articles, get headers, get bodies, post articles
    *** glibc detected *** double free or corruption (!prev):  
0x08067d98 ***
    Aborted
    $

I have tried re-emerging leafnode, emerging world & then `emerge -e  
leafnode` and it makes no difference. After this `revdep-rebuild`  
finds nothing to do, and so it still doesn't work.

Does anyone have any suggestions, please?
I think there may be some other command for fixing a systems binary  
dependencies, but I can't think what it is.

Further to this I've just discovered that I have two versions of gcc  
installed on my system. Could this be related?

    $ eix ^gcc$
    * sys-devel/gcc

Should I `emerge -C` one of these versions of gcc, or would that be a  
Dumb Idea?

I would make sure to run revdep-rebuild first to make sure nothing will
break.  If something links to it or gcc fails afterwards, it is a mess
to fix. 

Also run gcc-config -l and make sure which version you are using.  It
should have a little * next to the one you are using.

May want to wait on a serious guru to make sure of all this too.  This
can be one of those that you can't be to careful with.

Many thanks for your reply, Dale.
When I'm stuck on something like this it's really appreciated!

`revdep-rebuild` shows nothing needs fixing, but...

That shows the same as ` `which gcc` --version ` above:

    $  gcc-config -l
     [1] i686-pc-linux-gnu-3.3.6 *
     [2] i686-pc-linux-gnu-3.3.6-hardened
     [3] i686-pc-linux-gnu-3.3.6-hardenednopie
     [4] i686-pc-linux-gnu-3.3.6-hardenednopiessp
     [5] i686-pc-linux-gnu-3.3.6-hardenednossp
     [6] i686-pc-linux-gnu-3.4.6
     [7] i686-pc-linux-gnu-3.4.6-hardened
     [8] i686-pc-linux-gnu-3.4.6-hardenednopie
     [9] i686-pc-linux-gnu-3.4.6-hardenednopiessp
     [10] i686-pc-linux-gnu-3.4.6-hardenednossp
    $

I've never used `gcc-config` before.

Should I change to 3.4.6?

And what do I do then? `revdep-rebuild`? `emerge world`?

I'm hoping my further questions will prompt one to reply.  ;D
