>Description:
Trying to 'print siginfo_p->si_addr' in the attached test fails with:

 (gdb) p siginfo_p->si_addr
 There is no member named .

Although si_addr is a macro defined as:
#define si_addr _sifields._sigfault.si_addr

This worked on 6.8.

And struct siginfo does have those members.
>How-To-Repeat:
Build with gcc -g3 for the extra macro info.

b main; run; next;

 (gdb) p siginfo_p->si_addr
 There is no member named .
