Compiling it with
gcc -static -fcommon -o main.o -c main.c
gcc -static -fcommon -o a.o -c a.c
gcc -static -o main.exe main.o a.o
results in
$ ./main
myVar[0] = 5
myVar[1] = 6
myVar[2] = 7

Compiling it with
gcc -static -O2 -fcommon -o main.o -c main.c
gcc -static -O2 -fcommon -o a.o -c a.c
gcc -static -o main.exe main.o a.o
results in
$ ./main
myVar[0] = 0
myVar[1] = 0
myVar[2] = 0

Thus a different option causes this change.
