Runtime manager segfaults

[gbryant-arm]

Describe the bug
The runtime manager segfaults after some time repeatedly opening and closing TLS connections with Veracruz-Client.
This bug can be reproduced on Nitro and Linux.
Error message on Nitro:

[ 1975.584292] runtime_manager[594]: segfault at 9 ip 0000000000a6714d sp 00007ffde3018228 error 4 in runtime_manager_enclave[400000+1b3c000]

It seems to be caused by a memory leak in the runtime manager.

To Reproduce

• Deploy Veracruz (run PAS, server, runtime manager)
• Provision the same file in a loop:

  for((i=0;i<100000;i++)); do
  echo $i;
  $client_path policy.json \
      --data /input/file=file \
      --identity data_client_cert.pem \
      --key data_client_key.pem
  done
  

• Wait until the runtime manager segfaults

Expected behaviour
The runtime manager should be able to handle an infinite amount of successive TLS connections
