Thanks for testing this!  This change is not related to the NT_AUXV note in
fact (both just happened the same week).  What you should be looking for is
the readelf -l (objdump -p) output from the core file, for the segment with
vaddr 0xa000000000010000 (GATE_ADDR).  Check that its size is PAGE_SIZE.
You can also verify it in gdb while looking at the core file by checking
that e.g. "p (char *) 0xa000000000010000" shows "ELF\177" and that
"x/w 0xa000000000010000+PAGE_SIZE-8" (substituting the right PAGE_SIZE value)
works (and shows you zeros).


Thanks,
Roland
