Error: REVERSE_INULL (CWE-476):
    libvirt-0.10.2/src/util/processinfo.c:141: deref_ptr: Directly
    dereferencing pointer "map".
    libvirt-0.10.2/src/util/processinfo.c:142: check_after_deref:
    Null-checking "map" suggests that it may be null, but it has already
    been dereferenced on all paths leading to the check.
