Dynamically instantiated test suite + `cxxtestgen --no-static-init`: broken run-time behaviour

[mp-chet]

Overview

I have a dynamically instantiated test suite that contains a createSuite() method.
I call cxxtestgen with --no-static-init.

The resulting code misbehaves during execution as follows:

1. An instance A of my test-suite object gets created.
2. Another instance B of my test-suite object gets created.
3. setUp() is called on B.
4. The test-case methods are called on A, which is obviously uninitialised.
5. tearDown() is called on B.
6. B is destroyed.

Minimal example

Save this as bug.h:

#include <cxxtest/TestSuite.h>
  
class BuggyTestSuite : public CxxTest::TestSuite {

public:

    void setUp() override {
        std::cerr << "Calling setUp()        on " << this << std::endl;
    }

    void tearDown() override {
        std::cerr << "Calling tearDown()     on " << this << std::endl;
    }

    void testBreakage() {
        std::cerr << "Calling testBreakage() on " << this << " <- !!"
                  << std::endl;
    }

    static BuggyTestSuite *createSuite() {
        BuggyTestSuite *suite = new BuggyTestSuite();
        std::cerr << "Created " << suite << std::endl;
        return suite;
    }

    static void destroySuite(BuggyTestSuite *suite) {
        std::cerr << "Destroying " << suite << std::endl;
        delete suite;
    }
};

Steps to reproduce

cxxtestgen --error-printer --no-static-init -o bug.cpp bug.h
c++ -o bug bug.cpp
./bug

Example output

Created 0x557bfb48be70
Running cxxtest tests (1 test)Created 0x557bfb48c2c0
Calling setUp()        on 0x557bfb48c2c0
Calling testBreakage() on 0x557bfb48be70 <- !!
Calling tearDown()     on 0x557bfb48c2c0
.Destroying 0x557bfb48c2c0
OK!
