Hi,
I recently hit a SEGV in dlopen after upgrading to glibc 2.15
the stack looked like this
#0 0x0000000000005486 in ?? ()
#1 0x00007ffff7113685 in floor () from /usr/lib64/libm.so.6

After some researches I found out this commit :
http://sourceware.org/git/?p=glibc.git&a=patch&h=6ee65ed6ddbf04402fad0bec6aa9c73b9d982ae4
Backporting it fixed the issue, so it should be a good idea to backport it for
2.15.1
