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.
