Hello,
There are several places here where the return values of the
ports_create_class and ports_create_bucket functions are not checked.
In the
event of an out-of-memory situation, these functions may return NULL; we
should check the return value to avoid dereferencing a null pointer.
Thanks,
--

Subject: [PATCH 4/5] Added checks for ports_create_class and
ports_create_bucket return value in several place
