Another problem that could come up is that in one part of the code a function
argument is declared as a 32-bit quantity, and elsewhere it is 64 bits.
(Or vice versa.) This can occur, e.g., if #include files are included
differently in different source files.

I don't know of any systematic way of checking this.  Just standard debugging
techniques, but check that function argument values are the same in the calling
process and in the function itself.
