System: NetBSD klondike 1.1B NetBSD 1.1B (KLONDIKE) #99: Sat Mar 30 00:49:14 MET 1996 leo@klondike:/usr/src/sys/arch/pc532/compile/KLONDIKE pc532


>Description:
	On the pc532 /usr/bin/as does not terminate when compiling files
	containing floatingpoint constants in the form 0fInf.

	Also the ns32k architecture uses the ieee floatingpoint format,
	a special ns32k atof is used. I can see no reason for this and
	the code seems to contain a bug that causes /usr/bin/as to enter
	an endless loop when trying to convert a constant like 0fInf.
	The appended patch changes as to use atof_ieee instead of atof_ns32k.
	I didn't debug atof_ns32k because atof_ieee works for me.

>How-To-Repeat:
	$ echo ".double 0fInf" >/tmp/tst.s
	$ as /tmp/tst.s
