// Static variables coming from a C library through foreign function interface (FFI) are unsized
// at compile time - and assuming they are sized used to cause an internal compiler error (ICE).
// After this was fixed in #58192, this test checks that external statics can be safely used in
// a program that both compiles and executes successfully.
// See https://github.com/rust-lang/rust/issues/57876

//@ ignore-cross-compile
// Reason: the compiled binary is executed
