Segmentation fault during blob_client::upload_block_blob_from_stream

This issue looks similar to this issue from the azure-storage-cpp project: https://github.com/Azure/azure-storage-cpp/issues/265
(in that issue it was mentioned that there were indeed segmentation fault errors in azure-storage-cpp version 3.0 which where fixed later on).

Valgrind output of the error I'm getting:
