Compiler/MSP430FR2433: C++ object instances persistent in FRAM??

Tool/software: TI C/C++ Compiler

I want two instances of a class A to persist, in FRAM.
The class owns (has-a) an instance of another class B, which also should persist.
I want persistence because I am using LPM4.5.

When I try to init the persistent class instance, one of my assertion fails.

class B {
private:
    int value;
public:
    void init() {
        value = 0;
        assert(value == 0);  // <<<<< assertion fails
    }
    void increment() {value++;}
    int get() {return value;}
};

class A {
private:
     B b;
public:
     // just delegate to owned instance of B
     void init() {b.init(); }
     void increment() {b.increment();}
     int get() {return b.get();}
};


// Not initialized, and linker.cmd puts TI.noinit segment in FRAM
#pragma NOINIT
A a;
#pragma NOINIT
A another;

#pragma PERSISTENT
static int myCounter = 0;

main() ...omitted

My main() repeatedly sleeps LPM4.5 and wakes.
On coldstart, I call a.init(), which delegates to B.init.
The assertion in B.init() fails.

(On wake that is not a coldstart, I increment both myCounter and the instance a.
Then compares their values.
To make sure they both are persistent.
But I never get that far.)

I am using CCS 8.1.2 (I tried upgrade, but upgrade in Eclipse fails, I will need to reinstall?).
On Linux.
