Assertion failed: (ownership == ValueOwnership::Shared), function getVariableAddressableBuffer, file SILGenDecl.cpp, line 2352 #85785
Description
Compiling the attached SwiftPM project results in an assertion failure.
The overall structure of the project is
CAPI.h
typedef struct {
} indexstore_string_ref_t;Test.swift
import CAPI
struct IndexStoreUnitDependency: ~Escapable {
@inlinable
var name: IndexStoreStringRef {
@_lifetime(borrow self)
borrowing get {
let a = unit_dependency_get_name()
let stringRef = IndexStoreStringRef(a)
return _overrideLifetime(stringRef, borrowing: self)
}
}
}
struct IndexStoreStringRef: ~Escapable {
private let span: RawSpan
init(_ stringRef: indexstore_string_ref_t) {
fatalError()
}
}
func unit_dependency_get_name() -> indexstore_string_ref_t {
fatalError()
}This can be worked around by changing the parameter of IndexStoreStringRef.init from indexstore_string_ref_t to borrowing indexstore_string_ref_t.
