[sr-dev] Does shm_free() make the pointer NULL?

Hi, I'm realizing that a doble freeing occurs in regex module when it fails to start due to module params errors. But I'm sure it didn't occur in Kamailio 1.5. My question is the following:

static int *number; number = shm_malloc(sizeof(int)); shm_free(number);

Should now number be NULL? I confirm that it's NOT, so I get a double freeing since the function free_shared_memory() is executed twice and I check "if (number)" before doing "shm_free(number)".

So is it a change in 3.X? should I write:

shm_free(number); number = NULL;

?

Thanks a lot.
