It seems core.thread.Fiber doesn't work under the new DMD for win64.
Crashes on call(), in fiber_switchcontext(), access violation, looks like an
alignment problem, since the pointer is valid.


fiber_switchContext:
000007FEE25509E0  push        rbp  
000007FEE25509E1  mov         rbp,rsp

000007FEE25509E9  push        r14  
000007FEE25509EB  push        r15  
000007FEE25509ED  push        qword ptr gs:[fiber_switchContext+15h
(7FEE25509F5h)]  *** CRASH*** +15h? does 'push qword' support reading from
unaligned addresses like that?
000007FEE25509F5  push        qword ptr gs:[fiber_switchContext+25h
(7FEE2550A05h)]  
000007FEE25509FD  push        qword ptr gs:[fiber_switchContext+35h
(7FEE2550A15h)]  
000007FEE2550A05  mov         qword ptr [rdi],rsp  
000007FEE2550A08  mov         rsp,rsi  
000007FEE2550A0B  pop         qword ptr gs:[fiber_switchContext+43h
