InexactError: trunc(Int32, 6203998800) error when writing large file to S3 using Slimgroup's SegyIO

[memsermann]

Hello,
I am using AWSS3 to write to S3 using Slim SegyIO (https://github.com/slimgroup/CloudSegyIO.jl). In writing out very large files, e.g., > 10GB, we encounter a InexactError: trunc(Int32, 6203998800) error. Please see Stacktrace below: I believe this means that 6203998800 is too big to fit into a 32-bit integer. Is this something you could investigate and determine if this could have a quick resolution? We can read from S3 with no issues - only writing presents the error. Thanks for your help.

Do you have a MWE for reproducing this issue?

Also are you trying to write these files in a single PUT request? If so, you're going to hit the 5GB limit and realistically should be using multi-part uploads to perform these uploads.
