--- Comment #7 from Walfred Tedeschi <walfred.tedeschi at intel dot com> ---
It can be that x32 siginfo doe not implement the MPX specific part in it.
I.e. the _sigfault member could be written as:
struct
{
void *si_addr; /* Faulting insn/memory ref. */
short int si_addr_lsb; /* Valid LSB of the reported address.
*/
} _sigfault;
This is a first thought that comes into my mind.
Or we have new members not implemented yet in GDB.
