why it only symbolic the third parameter( the first and the second are fixed) in all paths?

[sandwich125]

 I use s2e to test grep programe,

the bootstrap.sh is as following:

  S2E_SYM_ARGS="1  2  3" LD_PRELOAD="${S2E_SO}" "${TARGET}" -D 2 $  ./text >/dev/null

but when s2e running out all the paths as 1.06 hours ,  the testcase generator all iputs as following. the first and the second parameter is fiex with  v0_arg1_0=  ***  "-D"  v0_arg1_1 = *** "2" , it only change the third parameter v2_arg3_2= **, why the forst and the second parameter is fixed ?

I have no idea. It pretty much depends on the program you are testing.
