In the example C file that causes the compiler to segfault, StructBase is not a pointer here, so this fails.

Here's a dump of StructBase:

MemberExpr 0x1240b890 'struct variable' lvalue ->growable 0x1240ac20
`-ImplicitCastExpr 0x1240b878 'struct bucket *' <LValueToRValue>
  `-DeclRefExpr 0x1240b858 'struct bucket *' lvalue Var 0x1240afe8 'p' 'struct bucket *'

So you have to distinguish between the MemberExpr and the pointer case right here, at which point you are basically back to my PR (although I guess the case for DeclRefExpr can be removed additionally; that does break tests, so I'll check carefully it the behavior is still correct with that case removed)

llvm::Value *Res = Addr.emitRawPointer(*this);

RecIndicesTy Indices;
getGEPIndicesToField(*this, RD, CountDecl, Indices);
