Bcrypt.verify() throws compiler error

[simonedelmann]

When running Bcrypt.verify() via swift run Run this always throws a compiler error.

Steps to reproduce

Add one of these lines to main.swift:

// Test BCrypt
let correctHash = try! Bcrypt.verify("password", created: "$2b$12$Ju7bigpFfjGCiIbqgx7W/uvieIMgj4.ppGLlsFN8j5KW2kOGavljS")

Expected behavior

This should result either true or false.
This should result true.

Actual behavior

When running via command-line (via swift run Run), this throws an compiler error:

Correct hash:

[1]    15147 segmentation fault  swift run Run

Wrong hash

Environment

I've used a fresh Vapor 4 template (March 25th 18:00 UTC), Xcode 11.4 Release, Swift 5.2 Release

@simonedelmann that's expected behaviour because WRONG isn't a valid hash so it's throwing an error. If the has wash valid, but was a hash for say password1234 then you'd get false.

@0xTim I see! Still the segmentation fault seems to be a bug. I will edit the issue above.

I'm able to re-create this but I have no idea what could be causing it. It seems to crash when calling bcrypt_hashpass which is part of the CBcrypt module.

I've opened an SR here: https://bugs.swift.org/browse/SR-12424

Closing this here since there's an SR-12424 tracking the issue.
