Hi Kenji,It appears to be a problem related to my DI generation patch. But I don't know near enough about cast.c to reduce the problem quickly, my guess is that druntime and phobos are excepting something to exist in the DI that the patch strips out, but that's only a guess. As you can see, the DI file itself is generated without any errors, this assert seems to come afterwards. Does D export the .DI file then try to use it during compilation of the .D file?
No it doesn't.
