I get a "Threading has been used before cthreads was initialized." crash for a simple program

program test;
uses cthreads;
begin
   writeln( 'Hello')
end.

on macos 14.2.1 with a fpc 3.3.1-14334-g5205ce30f4 snapshot, but the crash only occurs with mode -Mmacpas (which I assumes implicitely uses some unit that causes the issue).
