I am running Valgrind on my program. It shows me two errors but mentions only addresses against them and not actual code even on a debug build.

Could you pls. help me understand what it says and how to reach the erroneous line of code?

The errors are noticed in /lib/ld-2.3.4.so -- maybe that is NOT built for debugging?
Valgrind is not only showing addresses, but function names (within ld); the "dl" parts hint at "dynamic load". Something along run-time linkig may be going wrong.
