Yet another bug (core dumped)

[Dr. Jörn von Holten]

I'm using make 3.81rc1 and got a core with the following Makefile (a.cdl 
and b.idl exist)

---------------------
all: a.o b.o

a.o: a.cc
   touch a.o

a.cc: a.idl
   touch a.cc

a.idl:    a.cdl
   touch a.idl
   $(eval a.o: b.cc)

b.o: b.cc
   touch b.o

b.cc: b.idl
   touch b.cc

------------------------
The position is in remake.c:435 while evaluating  check_renamed (d->file)
as d->file is NULL.

You might now realize that I use the eval function at an "interesting" 
location, but
as the manual reads: "it can be placed virtually anywhere".
I expect that the rule is added to the makefile at that moment, the eval 
function
is evaluated as part of the a.idl rule and that Make takes it into 
consideration as well
and at once.
Background: I want new dependencies added dynamically that result from some
actions. I do not want to solve this by the remaking of makefiles, as I 
do not have rules
to generate missing makefiles (they shall be there or not), because I 
suspect that
by doing this, make will regenerate unwanted things - actually I 
generate the depend
files at the same moment I generate the targets.

Any suggestions? Maybe its possible to convince make to restart from 
"scratch" with
some other trick
