I believe this is caused by the convenience public static lets, since there's no function for the #function to pick up and the compiler doesn't handle that correctly.

struct Foo {
    init(x: String = #function) {
        print(x)
    }
    static let x = Foo()
}

Assertion failed: (SGF.MagicFunctionName && "asking for #function but we don't have a function name?!"), function getMagicFunctionString, file /Users/huon/swift6/swift/lib/SILGen/SILGenApply.cpp, line 4633.

Any chance of getting an eye on this in the relatively near future?

It looks like SILGenFunction::emitLazyGlobalInitializer should be setting this->MagicFunctionName in the same way as SILGenFunction::emitFunction (and others). A reasonable simple implementation would just use the name of the enclosing DeclContext (which is what's supported already), rather than trying to figure out a name for this specific variable.

Tagging as a starter bug.
