  • SR-11062 Compiler crashes when using attribute syntax with a property wrapper

Issue Description:

When initialising a property wrapper with a variadic argument while also passing an initial value for it's wrapped value, Swift raises an Abort trap: 6.

Both not supplying a value for wrapped value or not using a variadic argument resolves this crash.

Comment by Jari Koopman (JIRA)

I found out that this error also occurs for anything with an initial value in the initialiser (also non variadic). Should I open a new issue for this, or can this one be extended.

I think it's okay to track them together; it's probably not the variadic-ness that's the problem, then.

No longer crashes on master, I think this was fixed by one of Doug's PRs recently.
