Reproduce the crash with the shown example.c contents and clang-check --syntax-tree-dump, then inspect clang/lib/Tooling/Syntax/BuildTree.cpp around TreeBuilder::withTrailingSemicolon and processDeclaratorAndDeclaration. Done means the reproducer no longer triggers the assertion while syntax-tree dumping, with regression coverage for this malformed macro input.
