Compiler Crash - Associated with Typed Throw - Invalid InsertValueInst #81122
Description
Description
This issue appears to relate to Compiler crash with certain combination of parameters and typed throws #80264.
The commonality between this issue and the #80264 issue seems to be the typed throw.
Reproduction
struct MinimalExample {
// removing '-> Estimator' eliminates the crash
// removing the type from 'throws' eliminates the crash
func estimate() async throws(EstimatorError) -> Estimator {
return Estimator()
}
// removing any one of the properties of Estimator eliminates the crash
struct Estimator {
let kind: Kind
let index: Int
let stateA: Bool
let stateB: Bool
init() {
self.kind = .one
self.index = 0
self.stateA = false
self.stateB = false
}
}
enum EstimatorError: Swift.Error {}
enum Kind {
case one
}

Command SwiftCompile failed with a nonzero exit code
Expected behavior
The compiler should not crash.
Environment
swift-driver version: 1.120.5 Apple Swift version 6.1 (swiftlang-6.1.0.110.21 clang-1700.0.13.3)
Target: arm64-apple-macosx15.0
Additional information
This issue arose immediately after updating Xcode to Version 16.3 (16E140).
The actual code that triggered the crash was buried deep in a large file in a large framework.
It took me a while to realize the the error was pointing to a specific file. The file name is referenced in part 3 of the error message, just before the stack dump.
It then took much longer to identify the code at issue in the file. Eventually, I separated the code into a dozen separate files, and, in that fashion, was able to narrow the issue down to a method with a typed throw. Eliminating the type restriction on the throw eliminated the crash.
Obviously, that solution is merely a work around pending the bug being fixed.
