frexp(0.0, &x) hangs on ELXSI

[Richard O'Keefe]

MACHINE
	ELXSI

OPERATING SYSTEM
	Allegedly "4.3 BSD"

The ELXSI announces itself as
	ELXSI 4.3 BSD UNIX #1140_1: Mon Oct 17 14:01:46 1988
and /usr/man/man3/frexp.3 starts out
.\"     $Header: frexp.3,v 1.1 88/08/21 22:07:32 jcw Exp $ ENIX BSD
.\"
.\" $Log:       frexp.3,v $
.\" Revision 1.1  88/08/21  22:07:32  jcw
.\" Initial revision
.\" 
.\"
.\"     @(#)frexp.3     6.1 (Berkeley) 5/15/85
.\"
so this may be the appropriate group, even though the ELXSI uses COFF
and a V.2.2 adb.

COMPONENT
	The library function frexp(3)

DESCRIPTION

    main() {
	extern double frexp();
	double zero = 0.0;
	int scale;
	double result;

	result = frexp(zero, &scale);

    }

    The call to frexp() never returns.  Other arguments appear to work.
