I'm now porting a program from IA64 to x86_64 and encountered problems on=
 the segv_handler. I used struct sigcontext instead of siginfo_t and wrot=
e the function as=20
     segv_handler(int sig, struct sigcontext sc)
  but i can not get a proper failing address using sc.cr2.
  Could anyone help me?=20
