           Summary: assigment of enum value in struct with address space
                    attribute causes assert

code causing the assert. compile with command: clang -cc1 -o foo.bc -x c++
foo.cc

A code with a struct that has an address space attribute containing an enum
causes an assertion when a value is assigned to the enum field in the struct.

This code works with clang 3.0, broken only with relatively new ToT/3.1svn.


compile with command:

clang -cc1 -o foo.bc -x c++ foo.cc



gives error:





clang: SemaOverload.cpp:9786: clang::ExprResult
clang::Sema::CreateOverloadedBinOp(clang::SourceLocation, unsigned int, const
clang::UnresolvedSetImpl&, clang::Expr*, clang::Expr*): Assertion
`Result.isInvalid() && "C++ binary operator overloading is missing
candidates!"' failed.
