nice test case.

the reason "out of fixed registers" is not output is that Bprint
is used by diag.  abort() does allow bio buffers to be dumped,
and doesn't seem useful.

here's the 9atom solution:

; 9diff txt.c
/n/sources/plan9/sys/src/cmd/8c/txt.c:310,317 - txt.c:310,316
  		for(i=D_AX; i<=D_DI; i++)
  			if(reg[i] == 0)
  				goto out;
- 		diag(tn, "out of fixed registers");
- abort();
+ 		fatal(tn, "out of fixed registers");
  		goto err;

  	case TFLOAT:
