Description

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?

I'm going to close this as stale. While there's no guarantee the bug has been fixed, this bug is over a decade old and hasn't been addressed. Moreover it's for a platform that is seeing little to now use nowadays (x86). Finally, using lld-link will get you much better results nowadays.

Reopened because it's still an unresolved bug.

@walter: Then it should be transferred to https://github.com/DigitalMars/optlink
