Bug ID: 71320
Summary: filesystem::permissions does not respect
add_perms/remove_perms
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org

reproducer.cpp
filesystem::permissions ignores add_perms and remove_perms, instead always
setting the file permissions to the specified value.
For example:
permissions(file, perms::owner_all);
assert(status(file).permissions() == perms::owner_all); // works
// Add some additional permissions
permissions(file, perms::group_all | perms::add_perms);
assert(status(file).permissions() == (perms::owner_all | perms::group_all)); //
FIRES
assert(status(file).permissions() == perms::group_all); // Doesn't fire
