problem on handling SIGSEGV

Sat May 6 07:32:03 UTC 2006

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 wrote the function as 
     segv_handler(int sig, struct sigcontext sc)
  but i can not get a proper failing address using sc.cr2.
  Could anyone help me? 
  kernel is 2.4.22
  ur attention is appreciated.
