The last command will report "No memory leaks". But it is a bogus and useless 

I've added an explicit leak in the program and that last command still 
reports "No memory leaks", even though valgrind sees the increase in leaked 

This is probably due to the fact that valgrind replaces the calls to malloc, 
realloc and free while mtrace counts the leaks produced by these functions 
(that are no longer used when run under valgrind).

So, till I get some better solution, I'll stick with the valgrind suppression
