I had a look in the update log and it was indeed the GNU libc, libc6 and some other updates related to embbeded but no matter how i tried i couldn't take a screen shot
of the updates in order to post them here.
I will try again tomorrow.
BTW i was flying all morning long mission without a problem with the new arm-embbeded.

Also please have in mind that this happened with Ubuntu 12 LTS .

Hi Felix
I am almost certain that Ubuntu 12 LTS did an upgrade in libc two or three days ago and that caused my problem because i tested the whole aircraft
Monday and it worked fine for hours.
Is there any way to check what updates were installed the last 3 days?

Hm... so which exact arm-none-eabi-gcc package/version were you using that was failing?
So that we can warn others about this and put it on the wiki page...

It looks like the problem was coming from an updated by ubuntu compiler because after i installed the new paparazzi arm-embedded and  completely removed manually previous versions of the compiler, the system works fine.I will keep testing it for the whole day just to be sure.
The new compiler was installed with instructions found here:

FYIfor those using Ubuntu and the gcc-arm-embedded toolchain installed via Debian package:
The old PPA maintained by Terry Guo has been replaced by team-gcc-arm-embedded and the package renamed to gcc-arm-embedded:
