<pre><a href="https://github.com/rust-lang-nursery/rust-bindgen">https://github.com/rust-lang-nursery/rust-bindgen</a> crashes when ran on:
class BrowsingContext {
auto Tie(void* aUnused) const;
};
When trying to call getSizeOf on the auto type.
LLVM asserts:
/home/emilio/src/llvm-project/clang/lib/AST/ASTContext.cpp:2052:
clang::TypeInfo clang::ASTContext::getTypeInfoImpl(const clang::Type *) const:
Assertion `!A->getDeducedType().isNull() && "cannot request the size of an
undeduced or dependent auto type"' failed.
Got a patch, just figuring out how to write a test :)</pre>
