Having said that, I am a bit curious how you came to this patch.
Was the issue found by code inspection, or did you actually have a
real life use case to raise the core.bigFileThreshold configuration
to a value above 4GB?

Real life use - tracking changes in larger files.

Raising the limit above 4GB suddenly resulted in a broken pack files in the repository and
aborts of various git commands.

Data is still recoverable with all size sanity checks disabled.
