Valgrind not showing line numbers - Yosemite 10.10.3

Question

I'm doing the chapter in Learn C the Hard Way about Valgrind, but my line numbers aren't showing up despite using -g. I'm running Yosemite 10.10.3 and Valgrind 3.10.1.

My Makefile:

CC = gcc
CFLAGS=-Wall -g -static

FILES = ex1 ex3 ex4

all: $(FILES)

ex1: ex1.c
    $(CC) $(CFlAGS) -o ex1 ex1.c

ex3: ex3.c
    $(CC) $(CFlAGS) -o ex3 ex3.c

ex4: ex4.c
    $(CC) $(CFlAGS) -o ex4 ex4.c

clean:
    $(RM) $(FILES)

and my ex4.c file: (Intentionally broken)

#include <stdio.h>

int main(int argc, char *argv[]){
    int age  = 18;
    int height;

    printf("I am %d years old.\n");
    printf("I am %d inches tall.\n", height);

    return 0;
}

I've looked at this, which is my exact issue through on Ubuntu but the solution isn't working for me. I've also created my .dSYM file. My valgrind output is:

MacBook-Pro:c jaredramirez$ valgrind --dsymutil=yes --track-origins=yes

Thanks to @JonathanLeffler for helping me solve the issue. After his comment, I changed my Makefile to:

CC = gcc
CFLAGS=-Wall -g -static

FILES = ex1 ex3 ex4

all: $(FILES)

ex1: ex1.c
    $(CC) $(CFLAGS) -o ex1 ex1.c

ex3: ex3.c
    $(CC) $(CFLAGS) -o ex3 ex3.c

ex4: ex4.c
    $(CC) $(CFLAGS) -o ex4 ex4.c

clean:
    $(RM) $(FILES)

and the line numbers are showing up and the warning: no debug symbols in executable (-arch x86_64 error is gone.
