>Release:        1.5.1
>Organization:
	itojun.org
>Environment:
Architecture: i386
Machine: i386
>Description:
	it seems that 1.5.1 userland was compiled with floating point compiled
	into binaries.  therefore, if you install 1.5.1 userland onto
	machines without floating point (machdep.fpu_present = 0),
	it won't work.
>How-To-Repeat:
	get a machine without FPU, and try to run 1.5.1.  for example, ping6(8)
	that came with 1.5.1 tar.gz dies with SIGBUS.  /bin/ps also dies with
	garbled output (due to floating computation mistakes in screen width).

Program terminated with signal 10, Bus error.
