The comment describes a requirement on what happens for [*], but that branch in the code isn't restricted to cases involving [*]; it covers any case where (the type is a VLA and) groktypename has returned an expression to be evaluated before the type name. E.g. take your vla-stexp-1.c test but with sizeof(typeof(...)) instead of sizeof(...) - that aborts, but I'd hope such a fix in c_expr_sizeof_type would make it pass. -- Joseph S.
