You missed the "..._then_ function C _and then_ function D..." part :)

So my example would look more like:

static int functionB(void) {
        uint8_t localB[32];
...
}
static int functionC(void) {
        uint8_t localC[32];
...
}
static int functionD(void) {
        uint8_t localD[32];
...
}
int functionA( int a ) {
        functionB();
        functionC();
        functionD();
}

When gcc inlines all the functions into functionA it allocates 96 bytes 
of stack, because it isn't capable of reusing the stack space anymore.
