tilemaker built on the same machine according to instructions in #687 (comment)

I have been testing tilemaker on increasingly larger GeoFabrik extracts. Above a certain file size, the application crashes immediately after the "Reading .pbf" message. I found the limit between
us-midwest (2 129 162 240 bytes) works
britain-and-ireland (2 185 531 392 bytes) crashes

I'm not really a developer and certainly not a c++ dev, but this smells to me like it's related to the limit of a signed 32 bit integer somewhere.

If it helps, on a Linux system I've not seen that.

At 27/10/2024 00:14 I ran https://github.com/SomeoneElseOSM/SomeoneElse-vector-extract/blob/main/update_vector.sh using "Britain and Ireland", which at the time was around 2180837777 (i.e. more than 2147483648) without any immediate crash. After that date I ran into OOM issues but that's entirely down to the test machine (a Hetzner CAX21) that I was using.

The tilemaker version was built from source on 26th May so would be whatever was current at that time.
