Below you will find the last part of the build log (probably the most relevant part, but not necessarily). If required, the full build log is available here: https://people.debian.org/~sanvila/build-logs/202610/ About the archive rebuild: The build was made on virtual machines from AWS, using sbuild and a reduced chroot with only build-essential packages. If you cannot reproduce the bug please contact me privately, as I am willing to provide ssh access to a virtual machine where the bug is fully reproducible. If this is really a bug in one of the build-depends, please use reassign and add an affects on src:rust-test-fork-macros, so that this is still visible in the BTS web page for this package. Thanks. -------------------------------------------------------------------------------- [...] help: consider wrapping the function in a closure | 46 | .unwrap_or_else(|arg0: syn::error::Error| syn::Error::into_compile_error(/* syn::Error */)) | +++++++++++++++++++++++++ ++++++++++++++++++ error[E0308]: mismatched types --> src/lib.rs:119:27 | 119 | try_fork(attr.into(), input_fn, supports_bench) | -------- ^^^^^^^^ expected `syn::item::ItemFn`, found `ItemFn` | | | arguments to this function are incorrect | note: there are multiple different versions of crate `syn` in the dependency graph --> /<<PKGBUILDDIR>>/debian/cargo_registry/syn-3.0.6/src/macros.rs:36:22 | 36 | $(#[$attr])* $pub $struct $name $body | ^^^^^^^^^^^^^^^^^^^^^^^^ this is the expected type | ::: /<<PKGBUILDDIR>>/debian/cargo_registry/syn-2.0.119/src/macros.rs:36:22 | 36 | $(#[$attr])* $pub $struct $name $body | ------------------------ this is the found type | ::: /<<PKGBUILDDIR>>/debian/cargo_registry/syn-3.0.6/src/item.rs:173:1 | 173 | / ast_struct! { 174 | | /// A free-standing function: `fn process(n: usize) -> Result<()> { ... }`. 175 | | #[cfg_attr(docsrs, doc(cfg(feature = "full")))] 176 | | pub struct ItemFn { ... | 184 | | } | |_- in this macro invocation = help: you can use `cargo tree` to explore your dependency tree note: function defined here --> /<<PKGBUILDDIR>>/debian/cargo_registry/test-fork-core-0.1.5/src/procmac.rs:295:8 | 295 | pub fn try_fork(attr: Tokens, input_fn: ItemFn, supports_bench: bool) -> Result<Tokens> { | ^^^^^^^^ = note: this error originates in the macro `ast_struct` (in Nightly builds, run with -Z macro-backtrace for more info) error[E0631]: type mismatch in function arguments --> src/lib.rs:120:25 | 120 | .unwrap_or_else(syn::Error::into_compile_error) | -------------- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | | | | | expected due to this | | found signature defined here | required by a bound introduced by this call | = note: expected function signature `fn(syn::error::Error) -> _` found function signature `fn(syn::Error) -> _` note: required by a bound in `Result::<T, E>::unwrap_or_else` --> /usr/src/rustc-1.96.1/library/core/src/result.rs:1616:4 help: consider wrapping the function in a closure | 120 | .unwrap_or_else(|arg0: syn::error::Error| syn::Error::into_compile_error(/* syn::Error */)) | +++++++++++++++++++++++++ ++++++++++++++++++ Some errors have detailed explanations: E0308, E0631.
