Research direction

Reproduce the failure with the shown struct, then inspect the NewTypeDecl path reported by cmd/gogensig/gogensig.go:134 and cmd/llcppg/llcppg.go:195. Determine how an array without a length should be handled and add or update coverage if the repository provides a relevant test location; done means this input no longer exits with the shown panic.
