Greetings... This is a really strange bug. The following Makefile causes GNU Make 3.54 to core dump but not GNU Make 3.48. Changing the Makefile by for instance removing the line 'dir: dir.o' or removing one of the elements of AMSMODULES seems to make the bug go away. yunexus$ ls Makefile Makefile~ core yunexus$ cat Makefile AMSMODULES= util.o bm.o io.o crc32.o queue.o groups.o databases.o field.o authorize.o userlog.o menu.o lastlog.o amsfunc.o quotas.o dir: dir.o libams.a: $(foreach filename, $(AMSMODULES), libams.a($(filename))) ranlib $@ yunexus$ make -v GNU Make version 3.54, by Richard Stallman and Roland McGrath.
