        <pre>So I went ahead and tested my theory by setting CFLAGS and CXXFLAGS to "-O2"
and then to "-O1".

First:
CFLAGS:          -O2 -Wall -std=c99 -Werror=implicit-function-declaration
-Werror=missing-prototypes -fno-strict-aliasing -fno-math-errno
-fno-trapping-math -fno-builtin-memcmp -g
CXXFLAGS:        -O2 -Wall -fno-strict-aliasing -fno-builtin-memcmp -g
-> game crashes

Then:
CFLAGS:          -O1 -Wall -std=c99 -Werror=implicit-function-declaration
-Werror=missing-prototypes -fno-strict-aliasing -fno-math-errno
-fno-trapping-math -fno-builtin-memcmp
CXXFLAGS:        -O1 -Wall -fno-strict-aliasing -fno-builtin-memcmp
-> game does NOT crash

That's with gcc (GCC) 5.3.0 on archlinux.</pre>
