[PATCH] D139741: [clang][CodeGen] Use base subobject type layout for potentially-overlapping fields

[Jordan Rupprecht via Phabricator via cfe-commits]

rupprecht added a comment.

I'm not sure what the libcxx failure was that caused you to revert this, but we also saw a clang crasher as a result of this. `clang/lib/AST/Decl.cpp:4300 in unsigned int clang::FieldDecl::getBitWidthValue(const ASTContext &) const: isBitField() && "not a bitfield"`. I'll try to reduce it.
