🚀 go-pugleaf

    I believe at least one of these bugs was reported before, but I didn't
    see either one during a quick check of the unexpired articles for this
    group. Sorry if these are repeats. The following makefile


MYLIB_SRCS = myfile1.c myfile2.c
MYLIB_OBJS = $(MYLIB_SRCS:%.c=mylib(%.o))

MYLIB_TMP = $(MYLIB_SRCS:%.c=%.o)
MYLIB_OBJS2 = $(foreach f,$(MYLIB_TMP),mylib($f) )

all :
	echo $(MYLIB_SRCS)
	echo $(MYLIB_OBJS)
	echo $(MYLIB_TMP)
	echo $(MYLIB_OBJS2)


    gives the following output:


sprite% gmake -k -n
echo myfile1.c myfile2.c
echo mylib(myfile1.o mylib(myfile2.o)
echo myfile1.o myfile2.o
Bus error - core dumped
sprite% 


    One error is in the generation of MYLIB_OBJS. Note the missing paren in
    the second line of output.

    The core file seems to be generated as a result of evaluating the
    foreach construct. For those interested in such things, the traceback
    follows.  (I wrapped the lines to avoid potential 80-column willies.)
