Guess what -- I can make `make' 3.54 dump core reliably.

I'm using a Sun4/260 under SunOS4.0.3.

Here's the makefile, which I named `GNUmakefile':

################################################################
TILDE = $(shell echo ~)
VPATH = $(TILDE)/fred

ho:
	@echo $(VPATH)
################################################################

type `make' in the same directory as this file.

If you're interested, here's a backtrace:
