[libvirt] [libvirt-php] memory overflow when using libvirt_list_networks



Finding lots of bad behaviour here:


[Fri Apr 17 23:44:04.590626 2015] [:error] [pid 31714] [client
127.0.0.1:38103] PHP Warning:  libvirt_list_networks(): this function is
not supported by the connection driver: virConnectNumOfNetworks
[Fri Apr 17 23:44:04.590655 2015] [:error] [pid 31714] [client
127.0.0.1:38103] PHP Fatal error:  Out of memory (allocated 524288)
(tried to allocate 18446744073709551608 bytes)


There's no way to check if this exists... I noticed the following about
versions:

- this system works fine (Git):
libvirt 1.2.9
Array
(
    [libvirt.release] => 9
    [libvirt.minor] => 2
    [libvirt.major] => 1
    [connector.version] => 0.5.0
    [connector.major] => 0
    [connector.minor] => 5
    [connector.release] => 0
)


- this system has problems (Git)
libvirt 1.2.12
Array
(
    [libvirt.release] => 12
    [libvirt.minor] => 2
    [libvirt.major] => 1
    [connector.version] => 0.5.0
    [connector.major] => 0
    [connector.minor] => 5
    [connector.release] => 0
    [type.release] => 12
    [type.minor] => 2
    [type.major] => 1
)



When I do a version check to only do network list for version under .12,
I get this:

[Fri Apr 17 23:44:43.608308 2015] [:error] [pid 31689] [client
127.0.0.1:38216] PHP Warning:  libvirt_network_get(): this function is
not supported by the connection driver: virNetworkLookupByName


Which causes a cascade of other errors if you're not checking for
problems each step along the way.
