6 years ago when I use old luna Makefile,program work normally.But when I add ASAN.then luna's Makefile is change to :
1
2 SRC = $(wildcard src/*.c)
3 OBJ = ${SRC:.c=.o}
4
5 CC = clang
6 PREFIX = /usr/local
7 CFLAGS = -std=c99 -g -O0 -Wno-parentheses -Wno-switch-enum -Wno-unused-value -fsanitize=address
8 CFLAGS += -Wno-switch
9 CFLAGS += -I deps
10 LDFLAGS += -lm -fsanitize=address
11
12 # MinGW gcc support
13 # TODO: improve
14
15 clang = $(shell which clang 2> /dev/null)
16 ifeq (, $(clang))
17 CC = gcc
18 endif
19
20 # deps
21
22 CFLAGS += -I deps/linenoise
23 OBJ += deps/linenoise/linenoise.o
24 OBJ += deps/linenoise/utf8.o
25
26 # test
27
28 TEST_SRC = $(shell find src/*.c test/*.c | sed '/luna/d')
29 TEST_OBJ = ${TEST_SRC:.c=.o}
30
31 CFLAGS += -I src
32
33 # output
34
35 OUT = luna
36 ifdef SystemRoot
37 OUT = luna.exe
38 endif
39
40 $(OUT): $(OBJ)
41 $(CC) $^ $(LDFLAGS) -o $@
...then I run luna with ./luna ./examples/array.luna. luna crashed. then there is luna crash information:
root@yhk-RH2485-V2:/home/lx/5_30/luna/ASAN/luna-master# ./luna examples/array.luna

Hello everyone.I use my company tools to fuzz test luna.But when it firstly run,luna is crash.So I dig to find the key problem. It is due to Makefile wasn't perfect.
when luna use old Makefile,luna wasn't crash.But when it use ASAN,luna crashed.Because Makefile is lack of -D_GNU_SOURCE make config. there is new Makefile.but when it use new Makefile,ASAN also print.ERROR: LeakSanitizer: detected memory leaks.So I want to show my process in fuzz test.
