I can't seem to reproduce, but:
* if the signature you report is a prototype, OK, I see the issue. It sounds like a bug in the C parser (why generate a local tag for a prototype??), but there is probably also an issue in the plugin as the rule `local.policy = FORWARD` should make it ignore it… at any rate, by default there's no generation for prototypes. * could you try and give a backtrace, to share the exact setup that causes the crash? (e.g. the source code + plugin config)
