  "message": "gccrs: Fix ICE cloning trait functions without return types\n\nFixes Rust-GCC/gccrs#3972.\n\nTrait functions without an explicit return type can have a null\n`return_type` in `TraitFunctionDecl`. When such declarations are copied,\nthe copy constructor and assignment operator currently try to clone the\nreturn type unconditionally, and this can lead to an ICE.\n\nHandle this case by keeping `nullptr` when there is no return type to\nclone. Also add a regression test for the example from Rust-GCC/gccrs#3972.\n\ngcc/rust/ChangeLog:\n\n\t* hir/tree/rust-hir-item.cc (TraitFunctionDecl::TraitFunctionDecl):\n\tHandle null return types in copy constructor.\n\t(TraitFunctionDecl::operator\u003d): Likewise.\n\ngcc/testsuite/ChangeLog:\n\n\t* rust/compile/issue-3972.rs: New test.\n\nSigned-off-by: lishin \u003clishin1008@gmail.com\u003e\n",
