Excerpt from the d.D newsgroup (Incremental compilation with DMD):

`Somewhere in the process a library is created that confuses OPTLINK as well as
"lib -l". There's one symbol in it that neither of these are unable to see and
it results in an undefined reference when linking. The symbol is clearly there
when using a lib dumping tool from DDL or "libunres -d -c".
(...)
it can be found via a regex "D2xf3omg4core.*ctFromRealVee0P0Z".`

My guess: there's a mismatch between the lib dictionary and its actual
contents. I can provide reproduction steps if necessary but they will be rather
involved. Maybe the intermediate .lib files and operations using the librarian
would be useful?
