I'm sorry about that, I'll get the preprocessed program sent to you.

I'm afraid I don't see the connection between the two reports.
In my case, memcpy is correct programmatically but it's triggering
an alignment error as it's performing 8-byte loads when the source
argument is 4-byte aligned (the destination is 8-byte aligned though).
