The check if v is valid is after it is used..
v initialized to 1-1==0
then you jump into this loop
when loop-block finished v-- is executed. v is now -1
then the argv expression above is evaluated, which should cause a
segfault.

Next problem: assignment done after the goto. You get by this since you
always assign file=stdin at program startup.
You compiler should have warned you here. Did you remember to use -Wall
when compiling your program?
