  "message": "Add a test component with malloc(0) returning NULL\n\nExercise the library functions with calloc returning NULL for a size\nof 0. Make this a separate job with UBSan (and ASan) to detect\nplaces where we try to dereference the result of calloc(0) or to do\nthings like\n\n    buf \u003d calloc(size, 1);\n    if (buf \u003d\u003d NULL \u0026\u0026 size !\u003d 0) return INSUFFICIENT_MEMORY;\n    memcpy(buf, source, size);\n\nwhich has undefined behavior when buf is NULL at the memcpy call even\nif size is 0.\n\nThis is needed because other test components jobs either use the system\nmalloc which returns non-NULL on Linux and FreeBSD, or the\nmemory_buffer_alloc malloc which returns NULL but does not give as\nuseful feedback with ASan (because the whole heap is a single C\nobject).\n",
