If I have a subroutine local variable (Real) that is allowed to be on the stack, I don't initialize the variable in the routine and call another subroutine and pass that variable as an argument (knowing the called routine will set it and return). Can there be a problem with FP Execptions? If the stack value is such that that varible ends up being NaN, can it cause the program to throw an exception by passing that NaN to the subroutine?
