--- Comment #1 from Adam D. Ruppe <destructionator@gmail.com> ---
Regression introduced some time after v2.098.0, works fine in that version.



More details off dmd master trying the bug:

test.d(2): Error: module `c` from file a/c.d must be imported with 'import c;'
test.d(2): Error: size of type `D` is not known

ERROR: This is a compiler bug.
Please report it via https://issues.dlang.org/enter_bug.cgi
with, preferably, a reduced, reproducible example and the information below.
DustMite (https://github.com/CyberShadow/DustMite/wiki) can help with the
reduction.
