[MLton] Bug in optimizations related to ref cells?

[Vesa Karvonen]

Quoting Stephen Weeks <sweeks@sweeks.com>:
> The bug is in refFlatten, which I discovered by compiling with

> so for now, you can survive by compiling "-drop-pass refFlatten".

Thanks for the tip! (My conversion of SRFI-45 is almost done.)

>  In the meantime, I am investigating the bug.

Great!
