Is there any solution to ltrace calls made by libs opened using dlopen()?

I wrote different two different types of queues. Bundled them in different .sos. I have a driver main.c which tests functions offered by those queues. main.c makes use dlfcn.h to load, unload required library at run-time. Both the implementations of queue make use of standard library functions. I wish to list number of mallocs and frees made by my library. So I did ltrace -c ./exe.out but, it could not catch any standard library calls made by my dlopen()ed libraries. All that ltrace could tap in was dl*() calls. I checked SEE ALSO part of man ltrace and so read man ltrace.conf too. But the manual itself is bit obfuscated for beginners like me! - How to trace calls made by dlopen()ed libraries using ltrace utility? - Does configuring /etc/ltrace.conf help me deal this situation?
