// When using foreign function interface (FFI) with C++, it is possible
|
|
// to run into a "double unwind" if either both Rust and C++ run into a panic
|
|
// and exception at the same time, or C++ encounters two exceptions. In this case,
|
|
// one of the panic unwinds would be leaked and the other would be kept, leading
|
|
// to undefined behaviour. After this was fixed in #92911, this test checks that
|
|
// the keyword "unreachable" indicative of this bug triggering in this specific context
|
|
// does not appear after successfully compiling and executing the program.
|
|
// See https://github.com/rust-lang/rust/pull/92911

|
//@ needs-unwind
|
|
// Reason: this test exercises panic unwinding
|
|
//@ ignore-cross-compile
|
|
// Reason: the compiled binary is executed
