### Summary When compiling code using #[derive(Default)], GCC-RS 14.0.1 fails with an internal compiler error (segmentation fault), while rustc-nightly compiles successfully with warnings. ### Reproducer I tried this code: ```rust...
### Summary When compiling a program using nested macros with decl_macro feature, GCC-RS 14.0.1 crashes with an internal compiler error while rustc-nightly compiles successfully (with warnings). ### Reproducer I tried...
### Summary The provided Rust code compiles successfully with rustc but fails with gccrs due to a type mismatch and an internal compiler error (ICE). The issues occur when initializing...
### Summary This code causes an error in gccrs, but rustc didn't report the error. The compiler experiences significant performance degradation when handling recursive calls and nested structures, leading to...
