Today i've studied the problem on my linux box (2.6.15.6), and i've written 
two case study samples on the false line of "xgc" message:

[jmp *%esp technic]
http://rawlab.altervista.org/codes/exp/randstack/exp_jmp_rand.pl

[call *%edx technic]
http://rawlab.altervista.org/codes/exp/randstack/exp_call_rand.pl

This second case study was developed trying to exploit famous "abo3.c" 
vulnerable program (see gera advanced overflow contest).

I hope you like that!
