Yum random crashes in XO4 f20 images

[Martin Abente Lahaye]

Hello Peter,

I am have been building a Fedora 20 image for the XO4, and I am seeing
memory corruption problems while running yum in these images (please check
the logs [1,2]).

To give you some context, we are using olpc-os-builder (master [3]) with
fc20 repositories plus a few hand-crafted packages such as the kernel,
systemd and xorg, taken from previous Daniel Narvaez efforts [4,5].

These crashes happens randomly when yum is running, by calling yum update
or when olpc-os-build is installing system packages.

James Cameron, who spent some time researching about this issue, speculates
that this problem could be caused by: (a) using older kernel that was
compiled (possibly) with different options compared to f20's, or (b) a
faulty glibc library.

I was wondering if this could be related to something else, something more
specific to  yum or python arm binaries (?).

I would sincerely appreciate any guidance you can provide to start
discarding possibilities and try to debug this issue.

Thanks in advance for any help you can provide!

Regards,
Martin.
