Description colin 2024-09-30 00:42:12 UTC

Works fine in the official Swift Docker image, but not on my Gentoo system

Reproducible: Always

Steps to Reproduce:
1. Create a project that uses SQLite.swift to open a database
2. `swift run`
Actual Results:  
Prints error at runtime:
```
sst: /var/tmp/portage/dev-lang/swift-5.10.1/work/swift/stdlib/public/runtime/Metadata.cpp:1577: (anonymous namespace)::FunctionCacheEntry::FunctionCacheEntry(const Key &): Assertion `false && "objc block without objc interop?"' failed.
fish: Job 1, 'swift run' terminated by signal SIGABRT (Abort)
```

Expected Results:  
It should successfully open the database

It's possible that the Docker image doesn't build Swift with assertions.

Comment 3 Itai Ferber 2024-10-09 17:57:06 UTC

Sorry about this! Indeed, I believe the Swift Docker images build without assertions, and we should be doing the same here too. I can confirm the crash trivially, but I haven't had the time yet to rebuild Swift 5.10.1 without assertions to confirm the fix (I'm still trying to get Swift 6.0.1 built and I have limited compute resources) — hoping to get to this soon!

Comment 4 Itai Ferber 2024-10-13 01:27:21 UTC

Confirmed that compiling Swift without assertions resolves the issue. Fix incoming in swift-5.10.1-r1.

This needs a new revision as it changes the installed binary (the bug itself involves runtime behaviour).

Comment 7 Itai Ferber 2024-10-13 15:22:25 UTC

Indeed, the change was introduced in a new revision (-r1)

Comment 8 Sam James archtester

Ah, the commit didn't make it obvious, you're right of course: https://gitweb.gentoo.org/repo/proj/guru.git/log/dev-lang/swift/swift-5.10.1-r1.ebuild.

Comment 9 Itai Ferber 2024-10-13 15:25:05 UTC

Yeah, sorry — I had a few reasons to introduce -r1 and I didn't want the individual changes to get lost; agreed that it was unclear! (And thanks for checking!)
