Determining base address of shared library from core file

[Bloch, Jack]

When doing this, I find a DT_DEBUG entry but is has a zero in the d_un.d_val
field (I am supposed to look at the executable and not the core dump right?)

It depends upon what you mean by "easy".

For an SVR4-like system (which includes Linux), you have to traverse
the dynamic section to find the address of the r_debug struct.  Once
that is done, you still have to traverse the link_map structs to find
the desired address.  See solib-svr4.c for the gory details.

(IMO, this isn't very easy.)
