lldb: .../clang/lib/AST/Decl.cpp:4188: bool
clang::FieldDecl::isZeroSize(const clang::ASTContext &) const: Assertion
`isInvalidDecl() && "valid field has incomplete type"' failed.
So importing just the type `E` is insufficient but I somehow cannot import the
variable `e`:
auto *FromE = FirstDeclMatcher<VarDecl>().match(FromTU,
varDecl(hasName("e")));
...
// ASTTests: .../llvm/include/llvm/Support/Casting.h:269: typename
cast_retty<X, Y *>::ret_type llvm::cast(Y *) [X = clang::DeclContext, Y =
clang::Decl]: Assertion `isa<X>(Val) && "cast<Ty>() argument of incompatible
type!"' failed.
llvm::Error Err = findFromTU(FromE)->Importer->ImportDefinition(FromE);
