Bug ID: 66078 Summary: 20_util/specialized_algorithms/uninitialized_copy/8085 90.cc fails with -std=c++11 Product: gcc Version: 6.0 Status: UNCONFIRMED Keywords: wrong-code Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: jason at gcc dot gnu.org CC: jwakely.gcc at gmail dot com Target Milestone: --- When compiled with -std=c++11, vector::_M_default_append ends up calling the template constructor for moving from the old array to the new one. This seems wrong as well as inconsistent with C++98; I would expect that the construction should be from T&& or const T&, not T&. This failed as far back as 4.7; I have not tested with earlier libraries.
