Bug ID: 44468
Summary: Cannot access members of temporary objects created via
CTAD
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++17
Assignee: unassignedclangb...@nondot.org
Reporter: tony.wasse...@gmx.de
CC: blitzrak...@gmail.com, erik.pilking...@gmail.com,

When creating temporary objects of deduced template argument type, clang fails
to compile a program that attempts to access a member of the created object.
Example: `MyTemplate { t }.a`.
A workaround is to wrap the created object in an std::move, like
`std::move(MyTemplate { t }).a`.
Interestingly, this issue only seems to happen when the constructor argument
itself is a dependent name.
Full example: https://godbolt.org/z/Tj6TC7 . GCC and MSVC consider this example
valid.
