noinitadaptor::destroy causes compiler error

[SquaredPotato]

Error states
/opt/boost/1_74_0/include/boost/core/noinit_adaptor.hpp:58:10: error: expected a class name after '~' to name a destructor p->~U();

Compiling on MacOS with Clang 10.0.0., with the -std=c++20 flag.
I'm not sure why, but the error disappear when I replace the template class "U", with any other letter like "T", so that it looks like this:

    template<class T>
    void samefunction(T* p) {
        p->~T();
    }

instead of

    template<class U>
    void samefunction(U* p) {
         p->~U();
    }

Is this issue specific to my system? I can't seem to find anyone else having this problem.

EDIT:
Fixed by placing
#define _TURN_OFF_PLATFORM_STRING at the top of my main.c file.

Check if you have a macro U defined somewhere.

Thanks for the quick response, it turns out it is indeed a macro defined by cpprestsdk in basic_types.h.
I guess this issue can be closed as it isn't a boost issue.

I ran in the same issue as you. Thanks for your edit. That saved my day!
