I completely turned off optimization and distcc.

In <io.c> I put the following debug statements:

  static VALUE
  rb_io_seek(io, offset, whence)
      VALUE io, offset;
      int whence;
  {
      OpenFile *fptr;
      off_t pos;

      fprintf( stderr, "rb_io_seek: A; whence=%d\n", pos, whence);
      pos = NUM2OFFT(offset);
      fprintf( stderr, "rb_io_seek: B; pos=%d, whence=%d\n", pos, whence);
      GetOpenFile(io, fptr);
      fprintf( stderr, "rb_io_seek: C; pos=%d, whence=%d\n", pos, whence);
      pos = io_seek(fptr, pos, whence);
      ...


The output still is

  seeking: 512 + 176
  rb_io_seek_m: whence=1
  rb_io_seek: A; whence=-1081830932
  rb_io_seek: B; pos=176, whence=0
  rb_io_seek: C; pos=176, whence=0
  now at: 176
