Analyzing this some more it seems to be:
  error_putstr("\n\n");
  error_putstr(x);         // x, if rbx, is "read error"
  error_putstr("\n\n -- System halted");
  while (1)
    asm("hlt");

>From my understanding of the ASM&C code I get for misc.o len should be stored in
RAX (which has a value of 0x1000 which for a long should not be negative?) unless
RAX go overwritten during callq instruction (or one of the later callq).
