Research direction

Start by compiling the provided snippet with the reported rustc version and inspect the parser entry points named in the backtrace, including parse_stmt_without_recovery, parse_full_stmt, and parse_expr_assoc_with. Done means this input no longer causes rustc to overflow its stack and crash, with regression coverage for the reproducer.
