// After modifying the span of a function, if the length of
// the span remained the same but the end line number became different,
// this would cause an internal compiler error (ICE), fixed in #76256.

// This test compiles main.rs twice, first with end line 16 and
// then with end line 12. If compilation is successful, the end line
// was hashed by rustc in addition to the span length, and the fix still
// works.

//@ ignore-none
// reason: no-std is not supported

//@ ignore-nvptx64-nvidia-cuda
// FIXME: can't find crate for `std`
