The shared lib has no debug info. That's why you don't get a file name
and line number.  If math.so is your own shared object read this:
http://valgrind.org/docs/manual/faq.html#faq.unhelpful

If it is a system lib you need to install a version that has debug info.
That depends on your distro and I can't help with that.
