Ah, sorry, I wasn't explicit enough.  How about this.  When Emacs 
freezes, print the requested values in the debugger and then continue 
with the "c" command.  I just now did that, with the following results 
for me:

$ gdb ./emacs
(gdb) source .gdbinit
(gdb) b fileio.c:5338
(gdb) r -Q
[In emacs, type C-x C-f abcdef RET, then type "x".]
Breakpoint 3, Fverify_visited_file_modtime (buf=27596677) at fileio.c:5338
5338      if (timespec_cmp (mtime, b->modtime) == 0
(gdb) p mtime
$1 = {
  tv_sec = 1421966150,
  tv_nsec = 791881570
}
(gdb) p b->modtime
$2 = {
  tv_sec = 1421966150,
  tv_nsec = 791881570
}
(gdb) c
Continuing.
[In emacs, type C-x C-s.]

  tv_nsec = 791881570
}
(gdb) c
Continuing.

Continuing.
