// A test for calling `C-unwind` functions across foreign function boundaries (FFI). | ||
// This test triggers a panic when calling a foreign function that calls *back* into Rust. | ||
// This catches a panic across an FFI boundary and downcasts it into an integer. | ||
// The Rust code that panics is in the same directory, unlike `c-unwind-abi-catch-lib-panic`. | ||
