  "message": "gdb, testsuite, fortran: fix double free in mixed-lang-stack.exp\n\nWhile testing mixed-lang-stack I realized that valgrind actually\ncomplained about a double free in the test.\n\n   All done\n  \u003d\u003d2503051\u003d\u003d\n  \u003d\u003d2503051\u003d\u003d HEAP SUMMARY:\n  \u003d\u003d2503051\u003d\u003d     in use at exit: 0 bytes in 0 blocks\n  \u003d\u003d2503051\u003d\u003d   total heap usage: 26 allocs, 27 frees, 87,343 bytes allocated\n  \u003d\u003d2503051\u003d\u003d\n  \u003d\u003d2503051\u003d\u003d All heap blocks were freed -- no leaks are possible\n  \u003d\u003d2503051\u003d\u003d\n  \u003d\u003d2503051\u003d\u003d For lists of detected and suppressed errors, rerun with: -s\n  \u003d\u003d2503051\u003d\u003d ERROR SUMMARY: 1 errors from 1 contexts (suppressed: 0 from 0)\n\nReason for this is that in mixed-lang-stack.cpp in mixed_func_1f an\nobject \"derived_type obj\" goes on the stack which is then passed-by-value\n(so copied) to mixed_func_1g.  The default copy-ctor will be called but,\nsince derived_type contains a heap allocated string and the copy\nconstructor is not implemented it will only be able to shallow copy the\nobject.  Right after each of the functions the object gets freed - on the\nother hand the d\u0027tor of derived_type actually is implemented and calls\nfree on the heap allocated string which leads to a double free.  Instead\nof obeying the rule of 3/5 I just got rid of all that since it does not\nserve the test.  The string is now just a const char* \u003d \"..\" object\nmember.\n",
