[cfe-dev] New failure in LibC++ tests on v4.0 branch

[Martin J. O'Riordan via cfe-dev]

Yesterday I updated to revision #294006 of the v4.0 branch, but I am getting
a few new failures in the C++ test-suite.  One example is:

 

llvm/projects/libcxx/test/std/containers/sequences/forwardlist/forwardlist.m
odifiers/emplace_front.pass.cpp

 

For which I get the following errors:

 

llvm/projects/libcxx/test/std/containers/sequences/forwardlist/forwardlist.m
odifiers/emplace_front.pass.cpp:28:12: error: non-const lvalue reference to
type 'T' (aka 'Emplaceable') cannot bind to a temporary of type 'void'

        T& r1 = c.emplace_front();

           ^    ~~~~~~~~~~~~~~~~~

llvm/projects/libcxx/test/std/containers/sequences/forwardlist/forwardlist.m
odifiers/emplace_front.pass.cpp:32:12: error: non-const lvalue reference to
type 'T' (aka 'Emplaceable') cannot bind to a temporary of type 'void'

        T& r2 = c.emplace_front(1, 2.5);

           ^    ~~~~~~~~~~~~~~~~~~~~~~~

llvm/projects/libcxx/test/std/containers/sequences/forwardlist/forwardlist.m
odifiers/emplace_front.pass.cpp:42:12: error: non-const lvalue reference to
type 'T' (aka 'Emplaceable') cannot bind to a temporary of type 'void'

        T& r1 = c.emplace_front();

           ^    ~~~~~~~~~~~~~~~~~

llvm/projects/libcxx/test/std/containers/sequences/forwardlist/forwardlist.m
odifiers/emplace_front.pass.cpp:46:12: error: non-const lvalue reference to
type 'T' (aka 'Emplaceable') cannot bind to a temporary of type 'void'

        T& r2 = c.emplace_front(1, 2.5);

           ^    ~~~~~~~~~~~~~~~~~~~~~~~

4 errors generated.

 

This is with a clean build, and I am compiling with '-std=c++14 -UNDEBUG'.
With my previous build based on revision #293059 this was working okay.  

 

Is this a known regression, or something new?

 

Thanks,
