  30 On some machines, gdb crashes when it's starting up while calling the
  31 vendor's termio tgetent() routine.  It always works when run under
  32 itself (actually, under 3.2, it's not an infinitely recursive bug.)
  33 After some poking around, it appears that depending on the environment
  34 size, or whether you're running YP, or the phase of the moon or something,
  35 the stack is not always long-aligned when main() is called, and tgetent()
  36 takes strong offense at that.  On some machines this bug never appears, but
  37 on those where it does, it occurs quite reliably.  */
