SubjectRe: 2.2.x kernels not filling in siginfo_t.si_addr on SEGV?

> Greetings!  Shouldn't a SIGSEGV fill in th si_addr member of the

Our group ran into this problem last summer while we were developing the
Oasis+ DSM system. We worked around it by utilizing the following code
fragment:

void fault_handler(int sig, siginfo_t *sip, ucontext_t *ucp)
{
void *addr;

addr = (void *) ucp->uc_mcontext.cr2;

...
}

Hope that helps.

Regards,
David
