Mencheck not giving detailed info on routines in Shared Libraries:

Although I can debug this fine with Totalview, and even use Totalview
memory debugger to find detailed location info on  memory leaks, Valgrind
(memcheck) is only giving me the vaguest info such as (below) :

Valgrind-3.13 (actually I compiled 3.15, but it says 3.13 with Valgrind
--version)

It should be possible to get more detailed info out of Valgrind(memcheck),
such as routine and line numbers ??
