> This is probably a mistaken assertion, because {{calloc}} is OK with zeros in
> arguments. From the man page:
> {code}
> The calloc() function allocates memory for an array of nmemb elements
> of size bytes each and re‐
> turns a pointer to the allocated memory. The memory is set to zero.
> If nmemb or size is 0, then
> calloc() returns either NULL, or a unique pointer value that can
> later be successfully passed to
> free(). If the multiplication of nmemb and size would result in
> integer overflow, then calloc()
> returns an error. By contrast, an integer overflow would not be
> detected in the following call
> to malloc(), with the result that an incorrectly sized block of memory
> would be allocated:
> malloc(nmemb * size);
> {code}
> {code}
> int n = qd_server->thread_count - 1; /* Start count-1 threads + use
> current thread */
> sys_thread_t **threads = (sys_thread_t **)qd_calloc(n,
> sizeof(sys_thread_t*));
> for (i = 0; i < n; i++) {
> threads[i] = sys_thread(thread_run, qd_server);
> }
> {code}
> Caused by https://github.com/apache/qpid-dispatch/pull/948; I missed the fact
> it is adding these new failures under Debug build.
