Windows: -1073741819 error code in rustup downloading with rustls

[djc]

See rust-lang/rustup#4173 (comment).

Claude says:

The error code -1073741819 is the decimal representation of the Windows status code 0xC0000005, which means STATUS_ACCESS_VIOLATION.
This indicates the program tried to read from or write to a memory address it doesn't have permission to access.

Would be useful to get a minidump for this if possible.

Yeah, we would need a minidump or some kind of other native stack trace information (like WinDbg attached to the rustup process...) to figure out where this is coming from. There's quite a lot of unsafe in the Windows verifier and I don't think squinting at every line is going to be efficient.

Its fairly weird that only some people manage to hit this crash though. Maybe there's something about their system configs causing parameters we pass in to be misused?
