Package: make
Version: 3.78.1-2

I am not at all sure if this bug is related to make (if it is, the
problem is upstream).  Maybe it's glibc.  I am having a lot of trouble
compiling things and could boil it down to a little setup I am going to
describe now.  It would be helpful if some people could try to reproduce
it and make suggestions on where it is comes from.  It seems it was
introduced in the last couple of weeks into Debian.

I have a directory with the following contents:
foobar:~/makebug$ find
.
./Makefile
./test
./test/cl_spushstring.h
./test/somedir
./test/cl_spushstring_append.cc
./test/cl_spushstring_push.cc
./test/cl_sstring.cc
./test/cl_sstring.h
./test/cl_st_c2.cc
./test/cl_st_concat1.cc
./test/cl_st_concat2.cc
./test/cl_st_concat3.cc
./test/cl_st_debug.cc
./test/cl_st_hashcode.cc
./test/cl_st_make0.cc
./test/cl_st_make1.cc
./test/cl_st_make2.cc
./test/cl_st_null.cc

All files are empty, except for the Makefile (see attachment).  When I run 

foobar:~/makebug$ /usr/bin/make diversion SUBDIR=test

I get the output

1   .
2   test
4   

While on older Debian/potato systems (and Solaris and so on) I get the
correct output (using upstream make-3.78.1).  Compiling make-3.78.1 on
Potato still shows the bug which is why I am so clueless about where it
comes from.

1   .
2   test
4   ./test/somedir/.

The target diversion was of course deliberately inserted to trace down the
problem.  It is simply

diversion:
        @echo "1   $(srcdir)"
        @echo "2   $(SUBDIR)"
        @echo -n "4   "
        @echo $(wildcard $(srcdir)/$(SUBDIR)/*/.)

If I rename some of the files or delete some, the error goes away.  If I
strip off stuff from the Makefile, the problem goes away as well.  But I
can reproduce it on two up-to-date potato machines and it doesn't seem to
be related to the FS, since it happens both on NFS and local ext2.  I have
tried strace to track it down but it remains mysterious to me.

The bug makes the library cln currently uncompilable on potato, it
complains about `no rule to make target...', since it must diverge down 
into test/subdir/, which it doesn't want to find. It is rather obscure to
me.

If you cannot reproduce it, try if you can build cln-1.0.3-2 from the
Debian sources.  It will most probably fail to link because of many 
missing objects.  If you still cannot reproduce it, please do contact me
again!

Regards
    -rbk.
