Bug#759530: 759530: segvault in strcmp-sse42
Hi,
what I'm seeing here is a segvault in strcmp-sse42.S, although I'm
not 100% sure that this is the only issue, but as the trouble arrived
with libc 2.19 I think the problem is somewhere in the new libc,
also as running an older kernel did not help at all.
currently the szstem is completely unusable, random segvaults,
also running into some major file system issues.
The problem shows up similar to to the original mail in this bug
report, during an upgrade of unrelated libraries.
