Thanks.

That's alpha.
On IA-64 the following segfaults:
#include <sys/mman.h>
#include <string.h>
#include <stdlib.h>

char buf[128] __attribute__((aligned(128)));

int main (void)
{
  int i;
  char *p = mmap (NULL, 65536, PROT_READ, MAP_PRIVATE | MAP_ANON, -1, 0);
  if (p == NULL) abort ();
  memset (p + 65536 - 26, 'T', 26);
  strncpy (buf, p + 65536 - 26, 25);
}

Will debug it.

tst-timer fails on sparc build too actually (well, there
it run for 3 hours until I killed that test, with exception of bug-regex12
all other tests succeeded).
On i686 and ia64 the reason is random value in sigev_notify_attributes.
It may well be 0 for you and you don't see the crash, for me it died on:
        newtimer->attr = *(pthread_attr_t *) evp->sigev_notify_attributes;
because evp->sigev_notify_attributes was garbage.
Will need to check sparc if that is the same reason or something else.
