Error on building ECDSA-verify example

[grandchildrice]

Hello, I am currently working on creating a comprehensive benchmark repository for zkVM. The results will be presented at ZKProof7 Workshop.

I have tested the ECDSA Verify guest code and am facing a puzzling error.

PR: grandchildrice/zkvm-benchmarks#12 (review)

It is during the verify of the Signature, I get the error DeserializeUnexpectedEnd . Since the exact same guest code is working fine on SP1-Turbo, RISC Zero, I am wondering if this is an error due to Jolt VM behavior. Any advice on this?

@grandchildrice have you tried giving the program more memory?

nice pfp btw!

Thank you! I will try it.

Your pfp is nice as well!
