DTLS enabled, bootstrapped wakaama client crashes if device management server is not available

[kiranpradeep]

1. Start Leshan bootstrap server having an entry for client. Stop the device management server if running.
2. Start DTLS enabled lwm2mclient to be bootstrapped.
3. Wait for the crash.

Attaching non_ipv4_ipv6_address_crash.txt

Note: Will need pull request #178 or else client crashes early on double free.

Code in sync with wakaama/master.
Compiler: Apple LLVM version 7.3.0 (clang-703.0.29)
Server: Leshan Bootstrap server 0.1.11-M11

Fixed by #178

@dnav There has been a misunderstanding. #178 is not a fix for this issue. It just helps get to this issue. Kindly don't close this issue. I am not sure how to fix this.

[dnav]

Sorry for that.
I do not pay the same attention to example code than to the core.

@dnav - I have been trying to resolve this issue. But, for the lwm2mclient(example) to take any action, the lwm2m_step() has to return an non zero value. During these steps, the lwm2m_step() always succeeds till the crash. Could you give some pointers on how to fix this ?

Of lesser importance: Is lwm2m_step() expected to return a failure when registration or update registration attempt fails ?

This is no more reproducible and closing.
