I wonder if that's caused by rev 1.2 of lib/libc/gmon.c (yes, back
from 1994 :)

revision 1.2
date: 1994/05/14 06:31:15;  author: cgd;  state: Exp;  lines: +3 -2
branches:  1.2.4;
rcsids.  also, avoid floating point when picking scale value.  doesn't
cost much, only done once.

-#ifndef hp300
+#ifndef notdef
 		s_scale = ((float)p->kcountsize / o ) * SCALE_1_TO_1;
 #else /* avoid floating point */
 		int quot = o / p->kcountsize;


I have that fixed to #ifdef in my tree for ~ages, b/c istr I once
encoutered similar softdep problems.

Please, can you confirm that it fixes the softfloat build for you?

Thanks.

SY, Uwe
