redefinition of ‘bool __tls_guard’ in orm/tiny/concerns/hasattributes.hpp:412

[SchaichAlonso]

Hi

GitHub actions' ubuntu-22.04 runner is failing to process statements in orm/tiny/concerns/hasattributes.hpp:412 and orm/tiny/concerns/queriesrelationships.hpp:71, claiming a redefinition of bool __tls_guard

Reproducer
CI Run
Maybe related issue: gcc#66944

Visual Studio claims thread local storage class was not valid there, too, though unlike GCC, MSVC compiles the code nevertheless

That doesn't look good.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66944 I think this page may be helpful.

I met the same problem.
and I solved the problem by adding the static thread loacl variable to static member function
like:
static auto &get_X{
static thread_local X;
}
