Nice catch, also weird that PAL is using unsigned int for size_t.

I don't have an Arm32 device to confirm though, not sure how to proceed.

I don't think there's ever been an Arm Linux build; (unless perhaps as a brief experiment ages ago) this isn't a bug it's porting work that's not been done.

When I was working on the Apple Silicon port I half hoped to get Ubuntu Arm working at the same time but I had a lot of difficulty setting up a working dev environment and gave up.
