gdb is the beast you need. Compile with -g, and don't use -O2 (or
-OsomethingOptimized).

What you are looking for is "bt". Inside the debugger, type "help bt".
It should give you info sufficient to see not only the calls, but the
arguments passed. If you are using threads, it gets more complicated,
and generally you'd need a patch for threads under stock gdb.
