What is the signature of the function being called? You say that
pointers are being passed in, but what does the function expect? For
example, is the compiler automatically creating an object for the string
constant using a default constructor? (I realize the loss record is
longer than the string constant, but I don't know what the function
expects.)
Also, is the function in a .so file that has been stripped so that
Valgrind cannot follow its stack trace?
And of course, what version of Valgrind are you using?
