When compiling my project using v2.098.0 or v2.098.1 on Windows 10, this error just appeared:

: fatal error LNK1318: Unerwarteter PDB-Fehler: OK (0) "".
Error: linker exited with status 1318

"Unerwarteter PDB-Fehler" means "Unexpected PDB-error". The next 3 attempts to compile yielded the following errors:

libucrtd.lib(lseek.obj) : fatal error LNK1318: Unerwarteter PDB-Fehler: OK (0) "".
Error: linker exited with status 1318

libucrtd.lib(initcon.obj) : fatal error LNK1318: Unerwarteter PDB-Fehler: OK (0) "".
Error: linker exited with status 1318

libucrtd.lib(round.obj) : fatal error LNK1318: Unerwarteter PDB-Fehler: OK (0) "".
Error: linker exited with status 1318

The obj file reported seems to pretty much be picked at random. In the first error message there simply was no lib/obj mentioned. This issue started appearing today, without installing any updates (to any program at all). The PC wasn't even shut down since yesterday, when everything worked fine. Restarting doesn't help, removing all obj files and doing a full rebuild also doesn't help (I have obj files built by MSVC that also get linked). I was on v2.098.0 before, then upgraded in hopes of fixing the issue. The very first compile after upgrading to v2.098.1 worked, every consecutive compile after that is broken again.

Forgot to mention: I'm using DMD, and the Windows 10 is 64 bit.

OOOOoops this went into the wrong forum! Sorry! I will repost this as a compiler issue, any moderator feel free to delete this post.

Are you using dub? if the problem appeared over night, then it sounds like a cache issue, probably due to windows antivirus

dub clean and delete the .dub folder, and see if that works

I got a similar issue once if a process (symbol server registry or something) locked the PDB files and the linker wasn't able to update the file but silently ignores it.

However, this doesn't smell like a compiler issue. Manually removing all PDB files could help. Those may are cached in some temp folders outside the project too.
