Re: [PATCH] Fix PR debug/19345

Are all types supposed to have a TYPE_STUB_DECL, regardless of where they were created?

I'm not sure. Every time I try to understand TYPE_STUB_DECL I get confused. Only Jason Merrill seems to have a firm grasp on that.

If so, then i also believe this bug is somewhere in the frontends, not creating a TYPE_STUB_DECL for the type "created" in the asm.

If not, then i believe the bug is what the patch fixed: That, if not all type's have a TYPE_STUB_DECL, then we need to be prepared to handle this case, and do something sensible.

There's a third possibility: for types with no TYPE_STUB_DECL, use DECL_CONTEXT on the TYPE_DECL you do have.

I would suggesting asking Jason; he might have an answer to your first key question: is this a front-end bug?
