__M_lock is a reserved name, so your code has undefined behaviour.

The same applies to most of the other names you've used.

Don't use names reserved for the implementation.

__raw_clr_flag is a function template, you need to tell the compiler
which specialization you want to use, i.e. __raw_clr_flag<T>.

__raw_clr_flag is also a reserved name. Undefined behaviour.
