Segfault in CRUDService.read() #535
Description
Hi. I'm seeing a segmentation fault in CRUDService.read() if I call this method multiple times in the same script:
from ydk.services import CRUDService
from ydk.providers import NetconfServiceProvider
from ydk.models.cisco_ios_xe import CISCO_CDP_MIB
from ydk.models.cisco_ios_xe import IF_MIB
address = '172.26.47.103'
username = 'admin'
password = 'cisco123'
provider = NetconfServiceProvider(address=address,
username=username,
password=password,
protocol='ssh',
port=830)
crud = CRUDService()
cdp = CISCO_CDP_MIB.CiscoCdpMib()
cdp = crud.read(provider, cdp)
if len(cdp.cdpcachetable.cdpcacheentry) > 0:
print("**** CDP neighbor count: {}".format(len(cdp.cdpcachetable.cdpcacheentry)))
else:
print("**** There are no CDP neighbors")
intf = IF_MIB.IfMib()
intf = crud.read(provider, intf)
print("**** Interface count: {}".format(len(intf.iftable.ifentry)))
The above script seg faults:
~/git/sdapov% python issue.py
**** CDP neighbor count: 1
[2] 59312 segmentation fault python issue.py
However, if I reverse the order of operations and call crud.read() against the IF_MIB first, the script runs fine:

I appologize, but I don't know how or where to start debugging this.
