There's this problem on the recent gcc-6.1:
In file included from conf/domain_conf.c:37:0:
conf/domain_conf.c: In function 'virDomainChrPreAlloc':
conf/domain_conf.c:14109:35: error: potential null pointer dereference [-Werror=null-dereference]
return VIR_REALLOC_N(*arrPtr, *cntPtr + 1);
^~
./util/viralloc.h:158:73: note: in definition of macro 'VIR_REALLOC_N'
# define VIR_REALLOC_N(ptr, count) virReallocN(&(ptr), sizeof(*(ptr)), (count), \
^~~~~
conf/domain_conf.c: In function 'virDomainChrRemove':
conf/domain_conf.c:14133:21: error: potential null pointer dereference [-Werror=null-dereference]
for (i = 0; i < *cntPtr; i++) {
^~~~~~~
GCC basically fails to see, that the
virDomainChrGetDomainPtrsInternal will never actually return NULL
because it's never called over a domain char device with _LAST
type. But to make it shut up, lets turn this function into
returning an integer and check in the callers if a zero value
value was returned.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
