Swift: Importing AK and querying type properties crashes swift-frontend in Debug build #1101

Open ADKaster opened 2 months ago

ADKaster commented 2 months ago

After #986, building with -DENABLE_SWIFT=ON and a -DCMAKE_BUILD_TYPE that is not Release or RelWithDebInfo causes swift-frontend to crash generating IR for TestAKBindings.swift.

Seen with Xcode 16 beta 5 in CI and locally, and beta 4 in CI.

Needs reduction and an upstream swiftc bug report.
