Hi,

We have seen the below crash in azure library recently.
Azure Storage Client Library for C++ (3.0.0)

Please let me known if there is any fix.

Using host libthread_db library "/lib64/libthread_db.so.1".
Core was generated by `/opt/qorestor/bin/ocafsd --node_no=0 --rpcport=9911 --dictdir= --nvm_journal_pa'.

Several segfault issue has already been identified after 3.0.0 and fixed. Can you try the latest version to see if the issue persist?
