Hello all,
I've spent all day beating my head against a crash in my windows build of this cross platform app. Here's the problem line:
let values = try url.resourceValues(forKeys: [.nameKey, .creationDateKey, .contentModificationDateKey])
It's specifically related to the creationDate or modificationDate keys. Checking for either one leads to a crash in swiftCore.dll... but here's the kicker - it only happens for files larger than 2gb?
Is there any way to symbolize swiftCore and Foundation? I'm using sentry to capture these crash reports, but I dont have symbols for much in this backtrace:

I confirmed this is file size related by taking a failing 3gb file and calling
fsutil file seteof <filename> 2147483647
and the file works... truncating a single byte larger fails.
The similar api in FileManager fails in the same way.
