Get AttributeError when running report for aws_hash_table_remove

I get the following error message:

When running the proof verification/cbmc/proofs/aws_hash_table_remove in AWS C Common branch. Use make report2 to run the proof.

The verification failed with an Out of Memory message.

Is this an issue with viewer or an issue with cbmc running out of memory?

This issue has been fixed. Thank you @markrtuttle
