----
the problem is that 'file->cmds' is NULL, on the second iteration through
this loop.
here is how I ran it:
make -t
here is my makefile:
------------------------------------------------------------
all: a
a:
echo $@
------------------------------------------------------------
the problem doesn't happen if I just do 'make a'; it has to
be a target which causes a dependency to be created.
(strictly speaking my stack trace above is from when I ran it on a
_real_ makefile, but I didn't recapture the output (it was the same)
after I created the much smaller test makefile and targets above)
