/* Invokes a system call with the stack pointer (%esp) set to a
|
|
bad address. The process must be terminated with -1 exit
|
|
code.
|
|
|
|
For Project 3: The bad address lies approximately 64MB below
|
|
the code segment, so there is no ambiguity that this attempt
|
|
must be rejected even after stack growth is implemented.
|
|
Moreover, a good stack growth heuristics should probably not
|
|
grow the stack for the purpose of reading the system call
|
|
number and arguments. */
