Input parameter values as shown by the backtrace
deviating from their original caller values
may also have been caused by these input variables getting modified
*within* the function (some people in some cases tend to prefer
creating local variable copies to actively work on, for this reason).

However, three parameters in a row being NULL
might obviously point to a more systematic mem erase.
